    Evolution and Features of JavaScript

    JavaScript is an object oriented, dynamically typed, client-side scripting language. Although the name JavaScript does consists of the word Java. But both languages are very different. JavaScript is known to have a very difficult syntax and runs directly inside the browser, without using JVM (Java Virtual Machine). Using CSS, JavaScript is made to alter HTML hierarchy defined in markup. It is particularly used in instances where it is required to animate, move, transition, hide or show parts of a page, without refreshing an entire page from the server. JavaScript is also used during pre-validation or where logic is used on client machine. It helps save number of requests to the server.

    Almost everything in JavaScript is treated as a prototype object. Even variables and functions are treated as objects. Variable in JavaScript have constructors, properties and methods.  JavaScript allows easy conversion of one data type to another type. Data type can be assigned at runtime and change during run time as well.

     

    Client Side Scripting

    Client Side Scripting does not rely on a server to process code or return results. Rather the code runs on client machine. Other popular client side languages are Flash, ActionScript, VBScript and Java. The problem with other client side scripting languages is that they either run on few browsers or require special plug-ins to function. Both Flash and Java are losing support because of two main reasons. Firstly because Java and Flash both require special installations such as JVM and Flash Plugins, some devices such as Apple iPhones and iPads don’t support them because of security reasons. Secondly, both Java and Flash require regular updates which again are disliked by many users and also pose possible security risks. However JavaScript works well across most browsers and is highly acceptable. It is considered as the most important and dynamic client side scripting language.

    Advantages of Client Side Scripting

    1. Load on server is considerably reduced as processing happens on client side rather than server side.
    2. Improved user experience because of faster response to user events.
    3. Better interaction with HTML, thereby developing a desktop software like experience.

    Disadvantages of Client Side Scripting using JavaScript

    1.  It is possible that JavaScript is disabled by the client which does pose a difficult challenge to overcome.
    2. Though JavaScript has better cross browser acceptability than other Client Side scripting languages. But because of large dependency on browsers, it is possible that a Script that runs well on one browser returns and an error on another browser.
    3. JavaScript web applications are much tougher to debug and maintain.

     

    Evolution of JavaScript

    JavaScript originated as LiveScript. It was developed by Netscape in 1996 for their browser more popularly known as Netscape Navigator. The main purpose of introducing JavaScript was to have better control over Java applets used within the browser. Initially Microsoft’s Internet Explorer didn’t support JavaScript. But later on added support for Jscript.

    JavaScript was primarily used for graphic roll-overs, pop-up alert messages, scrolling text in the status bar, opening new browser windows and pre-validating user data in online forms. With the introduction of AJAX or Asynchronous JavaScript and XML, importance of JavaScript grew and it became a much popular and useful web development language. It allowed web pages to update sections through background server requests. The user felt that that the pages are loading in continuity when in fact they were not. This special effect using AJAX led to its usage by many top companies such as Google and Flickr, which further led to the creation of JavaScript frameworks, such as jQuery, Prototype, ASP.NET AJAX and MooTools. Recently more sophisticated MVC JavaScript frameworks such as AngularJS, Backbone and Knockout have been developed and are gaining high importance amongst many developers.

     

    Design Principles of JavaScript

    JavaScript has a reputation amongst developers for being tough. The reason for this is because of the bad practices used by developers which resulted in decreased code readability. Developers originally used JavaScript through inline HTML embedded hooks which increases the difficulty of Web Development. However a transition took place and developers started using JavaScript with software design principles in mind and started following best practices. There are various JavaScript layers that exist above and below HTML code. These optional layers are helpful in visualizing the concepts of JavaScript:

    1. Presentation Layer
    2. Validation Layer
    3. Asynchronous Layer

    Web Design That Generates Leads

    Unless they’re coming in from one of your amazing blog posts (you do have a blog, right?), your home page will be the first impression your future client or customer gets of you. It may be the only time they ever look at your business. You don’t want them to run screaming off into the distance. You want them to, you know, stick around and eventually maybe even buy your stuff or hire you. Here are some tips from a leading web design agency in Los Angeles, for designing a home page that generates leads. 

    Make It Professional

    The first step to designing a home page that generates leads is to make sure it looks professional. I’m sure you already know that you don’t want a website that looks like it’s designed by a kindergartener (although these days…)

    This isn’t the 90s. Slapping fifty different colors down on a black background with three JavaScript popups is a thing of the past. But you also can’t just stick your text into the basic WordPress theme and call it a day.

    You want a site that looks reputable. And that might cost some money. You should at least spend a bit for the pro version of a theme.

    Before you spend some bucks, though, do some research. Who are your competitors? Better yet, which of your competitors seem to be doing good business. What does their website look like? What do other professional sites in your field look like?

    Take some notes. Make some sketches. Yes, I know. It’s like school, but it’ll pay off in the end. You don’t want other people getting your business, just because your website looks sketchy.

    Now look at your notes. Can you make your website with a WordPress theme? Great! Go ahead!

    Need a fancier website. Find WordPress intimidating? Hire a web development firm. You’ll thank yourself later.

    If you’re making the web page yourself, here are a few tips.

    •        Leave some white space

    •        Keep clutter down

    •        Use one or two compelling images that represent what your company does

    •        Don’t do almost anything that looks like it walked out of the 90s

    Tell Them What You Do and How It’ll Help Them

    This may seem like a no-brainer, but when you're designing a home page, you should definitely make sure your potential customers or clients know what you do or what you sell. I don’t just mean something vague like “web designer.” Be specific, because your future customers are looking for specifics. Let them know you’re a web designer specializing in e-commerce sites or a ranch that sells, specifically, organic free-range dinosaurs.

    Once they know what you do, make sure your visitors know how what you do will benefit them. Your e-commerce site designs may increase their sales or their productivity. Your free-range dinosaur meat may give them vitamins lost since the dawn of time.

    Don’t forget to provide examples. If you do project work, such as designing web pages or editing books, link to a portfolio. That way customers can get an idea of what you do and how you do it.

    Give a Clear, Immediate Call-to-Action

    In order to design a home page that generates leads, you have to actually prompt people to do something that will add them to your list potential clients. Now, it may take a bit to reel in a new client. Or they may be ready to work with you right this moment. Either way, your home page should direct the visitor to do, well, something. And, for the eager visitor, it should do it before that visitor ever scrolls down. This should be your primary call-to-action, which means it should be something like “Get a Free Quote” or “Buy This Thing and Save 20%” or “Fill Out This Form and Get This Free Thing.”

    Personalize Your CTAs

    This will get a bit more complicated, but if you can you should personalize your CTAs. Hubspot says that personalized CTAs work 42% better than just plain old unpersonalized CTAs.

    What’s a personalized CTA? A personalized CTA adapts to your visitor. For instance, if your visitor has already filled out your newsletter form, you don’t want your CTA to prompt them to fill out the same form again. Instead, you might want offer them a free quote instead.

    Provide Social Proof

    You know what the best advertisement is? Word of mouth. Word of mouth, however, is a bit hard to set off just whenever you want.

    You know what’s almost the same as word of mouth? Testimonials and big name clients. Put a few on your front page to prove you’ve actually done something that someone likes.

    This is called social proof. Dr. Robert Cialdini did a study (see a write-up of it) where he encouraged people to reuse towels in a hotel. Cialdini found that more people reused towels if told that other people also reused towels than reused towels if told that reusing towels would mean the hotel would donate money to help the environment. In other words, social proof was an even more powerful motivator than altruism.

    Where do you get testimonials? Well, from your clients and customers. It’s not rude to ask. If people like your work, I’ve found they’ll be eager to give you a bit of help.

    Put Your Address and Telephone Number

    If you have a physical address, put it on your home page. If you have a telephone number, put it on your home page. They’ll make you look like you’re a real person. (You are a real person, right?)

    Keep Your Home Page Your Home Page

    One-page home pages are popular right now, but if you can’t keep your website sleek enough to fit one page, I’d suggesting putting some stuff a bit deeper. Put an example post or two on your front page, but give the rest of your blog its own space. Same with your portfolio. Basically, just don’t make your visitors scroll on for all eternity.

    Make Sure Your Website is Responsive

    Your whole website should be responsive, but pay special attention to how your home page design looks on mobile phones. Is the call-to-action still one of the first things your visitor sees. Is it still obvious what you do? Is the text large and readable? Can a visitor still fill out any forms, even if they’re on a phone?

    Basically, if you give your business card to someone and then they look up your website on their smartphone, will they be impressed or confused?

    Your home page is important. It's not just something you throw up because you're supposed to have a main page! It's not just a welcome mat. It is, in a way, your front window into the world. And, with a little thought, a home page can be designed so that it generates leads and brings you more business

    6 Things you need to Know to Design a Great Website User Experience

    A website that makes a visitor feel like it was designed just for them, does wonders in retaining those users and making them come back for more. Navigation, text, media and graphics are the primary factors which should be kept in mind while designing a website.

    Understanding how visitors browse through sites is important to determine the dos and don’ts of web development. Here, we are listing some tips that will improve your website’s user experience and navigation.

    Information is Important

    Imagine this: You visit a website which is attractive in design, but it doesn’t give you the information you need, or is overshadowed by the visuals. Will you stay on the website?

    Although design is a great factor in attracting visitors, it is not usually the design a user is looking for. A website that focuses on the design more than the information tends to be overwhelming to the visitor, leading to the user abandoning the webpage and searching for another source.

    A web development company should bear in mind to keep the design simple and uncluttered. Integrate designs and images in your website which will help the user easily determine what the site is about and where to look for certain information. If the design hinders the user in acquiring information, get rid of it and replace it with a design that aids the user in finding out what they want in a hassle-free manner.

    Be Responsive

    The saying “content is like water” is the basis of responsive web designs. Designing a website that is responsive means that content can be viewed easily in all devices—laptops, mobiles, tablets, you name it. Getting a responsive design for your website ensures that your visitors are not annoyed if they have to constantly zoom in to read the content while using a smartphone.

    Since 80% of internet users utilize mobile devices, it is important for a website designing company to understand that websites should accommodate mobile and smartphone users or be left behind in the competitive race of web development.

    Furthermore, Google has changed its algorithm and now ranks your website on the basis of how mobile-friendly it is. So if businesses want to improve the ranking of their websites, going mobile is a great option.

    Cut Down on the Page Load Time

    Whether you are standing in a queue, or hanging around for the lunch you ordered to arrive, waiting is frustrating. Waiting for a webpage to load is a similar experience and since, in this case, a user has the choice to leave the page entirely, this is commonly the option people opt for when a page takes too long to load. According to Radware, a two second delay in website’s loading time resulted in abandonment rates as high as 87%.

    Moreover, with a high page load time, businesses suffer more today than they did a few years back. In 2010, if a page took six seconds to load, it suffered a conversion hit of -40%. Today, the same time will take a hit of -50%. Users expect a sleek and friendly webpage where they don’t have to wait too long and it is up to the web development company to provide them that.

    You can use GT Metrix, Website Grader, and Google’s PageSpeed Insights to analyze your site’s speed and make fixes wherever required. Enabling browser caching and compression and optimizing images will minimize your page load time to a great extent.

    Be Visually Responsible

    Images are a great way to tell a story without words. Successful websites make the use of images on their home pages to tell the visitor what the business is about and what the visitor will get out of it. Too much of a good thing, however, is dangerous.

    As we’ve mentioned above, images hog a lot of bandwidth, which results in a high page load time for a website. To counter that, images should be scaled down or compressed so that bandwidth remains free and visitors to your website can enjoy a great website-user experience.

    Another thing to keep in mind, while designing a website, is that images should not be stock photos. Instead, use images of your own. Remember, the purpose of a website is to brand your image, and it won’t be possible if you are not using images of your own company/products.

    The Navigation Bar is Your Friend

    So, now that you have a responsive website with a simple, elegant design and have taken measures to reduce the page load time, you have ensured that a user will visit your website without hassle. The next step is to plan to make the visitor stay on your site, and here’s where the navigation bar comes into play.

    Navigation bar is a guide to your website, and if the guide is not helpful, the visitor will not be engaged and will promptly leave. According to a research by Forrester, if the first visit to a website is negative, 40% of the visitors will not return.

    When you are hiring a website development company to design a corporate website, discuss your content with them and the design for the navigation bar. Design director Daniel Alves comments that the navigation bar is “the most important design element on a website.”

    In order to create an interactive navigation bar, keep the design simple and easy-to-read. Since people read in a left-to-right pattern, it is advised to keep your products and services on the left of the bar and the “actions” on the right.

    Sharing is Caring

    Social sharing is the new boom. Integration of social media sharing buttons gives you the opportunity to make your visitors your advertisers. The more the people share your web pages on social networks, the more your exposure is increased. So embrace the practice of social media sharing and watch as the traffic on your website multiplies!

     

    Bottom line: Keep the user’s perspective in mind. If there is anything that annoys you while browsing sites, chances are that they will annoy other users, too, so it is best to employ those methods which help the user find exactly what they are looking for on your site without getting lost or overwhelmed by your website navigation. A user-friendly website will entice new visitors and turn them into regulars.
