Chart is one of the oldest form of displaying data or information on the paper or web page. This is extremely helpful in many cases where we need to represent various figures in graphical way. It lessen the effort of the writer to a large extend. For a web developer, the charting library is always works like a charm. Though there are a variety of charting tools developed in JavaScript, it is the responsibility of the web developer to select the best one for his application. Let us discuss what are the important factors that we should consider before we choose a charting library?
Input Data format: Well, charts can’t be developed without figures or data. These data are known as input data. While dealing with JavaScript charting library, we must consider the format of input data it requires for displaying on the web page. There are many formats that can be imported for the purpose like csv, JSON or XML etc. The best option is JSON; because it is easier to access and it is highly flexible. So choose a JS library that takes JSON file for importing the input data.
Cross Platform compatibility: In this new era, there are a hundreds of different devices that are being used for browsing purpose. Smart phones and tablets are being used extensively by the users. So, it is the responsibility of the web developer to choose the right and appropriate JavaScript library so that it can be compatible with all platforms. It should enable the JavaScript developer to handle with multiple platforms for displaying the chart without any hassle.
Customization options: Yes, this is yet another factor to be considered while choosing the best charting tool for your application. Many chart libraries have a lot of features to customize; but that comes at a cost of memory. So, if you are not going to use these features in your application then why you choose that tool. It will unnecessarily put burden on the application. So, choose the right tool for your application that will not only fulfil all your needs but also prevent unnecessary load on the application.
Look n Feel: Many times, we find certain theme or background to be suitable for our website. Similarly, certain libraries can provide you better look and feel to your application. Look and feel matters a lot from the user’s point of view. So, we can’t ignore its importance at any cost. So we must choose appropriate JavaScript library for our application.
Performance: As a smart web developer or may be front end JavaScript developer, you must be cautious for the performance of the web application. Sometimes, we find some libraries making the overall system not only slower but also inefficient. So, we should avoid these types of unreliable and un-optimized tools in our application.
Support: Last but the most important factor i.e. Support. We must think twice before we choose a library that has no or bad support reputation. A JavaScript web developer must select a tool that is highly reliable with 24x7 support service. This would help you leverage the benefits of JavaScript web development.

Java Script- Is a web library or language? Many times we find this query on internet. Developers usually have a perception about JavaScript that it is a web library but the fact is different. JavaScript is a fully fledged language!! We will discuss about this in latter section of this topic. But, for the time being we have to admit the importance of JavaScript in web development because, it is next to impossible for a web developer to develop enterprise standard dynamic web application without the help of JavaScript. JavaScript is extremely useful in developing interactive and dynamic web applications which are the key success factor the modern web application.
Importance of JavaScript in front end web development: Without JavaScript, the web page is like a dead page; because, we can’t see any dynamic effects or attractive visual effects on the web page. For a Dynamic web page, we must implement JavaScript in our web application. Moreover with the changing environment, it is really has a tremendous impact on the web industry while building web applications for the future ready devices like smart phones and tablets. JavaScript developers help the web page to come alive with its eye catching stupendous effects that will definitely enhance the user experience.
Why JavaScript is more known as a frontend tool: Web developers can’t think about dynamic web page development without JavaScript. From this, we can understand the priority of JavaScript in the industry. Well, there are hundreds of JavaScript libraries that can be used by the JavaScript developers for different interactive visual effects on the web page. Moreover, web developer understands the power of JavaScript for fast web application. Yes!! JavaScript is superfast. The run time of JavaScript is just lightening fast and hence, it has more priority on front end web development; because, the end user experience of any application decides the fate of any application. So, web developers take the advantage of speed of JavaScript while developing frontend user interface.
Moreover, there are many free JavaScript modules available in the web that can be integrated to your web application to give a new look and feel to the website. Many plugins are there which can definitely help the web developers in developing quick web application with same efficiency as expected.
Does it have the potential that of a fully fledged language: Well, JavaScript has popularity of being a front end language or tool. But, it is a fully fledged language just like C, C++, Java or .Net!! It can do all tasks what C++ or Java can do!! Moreover, you can develop an entire website using JavaScript!!! There are many modern frameworks which are developed in JavaScript are fully loaded to support all types of web services that may required during web application development.
So, You can do backend programming with JavaScript: JavaScript frameworks like AngularJS, nodeJS etc encourages the web developers or JavaScript developers to build enterprise standard web applications without any need of backend programming language like Java, .Net or PHP etc. All these frameworks have the potential to write and build backend development using just JavaScript only!! Moreover, these JavaScript frameworks are gaining a stupendous popularity in recent period due to much faster web application produced from them because, user demands fast web application for their smart phone and tablets. So, we can see a bright future of JavaScript as a fully fledged language in the industry. This would help you leverage the benefits of JavaScript programming.

A client-side scripting language, JavaScript is a powerful tool when it comes to developing websites or web applications. When used by a skilled developer, it can work impressively to enhance the user experience. It also provides rich features and components. Syntactically JavaScript is an easy language to master but it is often predicted as a difficult language to work with owing to its environment – the Web browser. The popularity of JavaScript can be estimated from the way the latest technologies utilize it as a supported language for developing desktop apps. There are several tools within this language that help in speeding up the coding process, optimize codes and test the scripts in various situations. Besides these, they are also applied for unit testing, check security vulnerabilities and as debugging tools. Here’s a list of JavaScript tools that the developers should be aware of: JS Nice: This helps in reading the JavaScript codes even if it is obfuscated. In this sort of a program the JS Nice suggests new identifier types as well as names automatically. By using advanced techniques for program analysis as well as machine learning it can learn the name and type regularities from vast amount of open source projects. Converse. Js: It is an open source chat app that can be used to connect to any Jabber or XMPP server. You will also find it in the footer of the webpages, such as, Facebook chat and acts as a support to one to one or multi-user conversations. This tool is used to decline or accept contact requests, set statuses, etc. Hitch: This provides an extension model for both HTML as well as CSS. Hitch is defined as a prollyfill engine for JavaScript. By using this tool the developers easily import and utilize features from CSS selectors that have been merely proposed or HTML widgetry that is based on the previous web components proposal. Responsive Nav: This is another JavaScript plugin that makes the creation of responsive menus a simple task for the developers. CSS3 transitions and touch events are used by this tool to ensure impressive performance. This also works well on screen readers even when the JavaScript is disabled. There are standalones in this plugin too. The developers can also make use of the callbacks for init, close and open events. amMap: To include an interactive map functionality to the webpages the developers make use of the amMap. It is sued to display the locations of an office or the route through which one daily travels, etc. A distributor map can also be created by applying this tool. In addition to these, the developers can also include images or illustrations as backgrounds or layers in the maps. This would make a huge difference in the presentation or the e-learning tools. Sequel.Js: For building the SQL query Squel.js is used as it strings conveniently through an object related to the API. It supports all kinds of SQL queries. It can work also on the browser. But the latter is not advisable as the queries in this case will be visible to all. Candy: Another open source chat app that has been created with the help of this language. It uses Jabber in developing real time based communication. The added advantage for this open source tool is that it receives support from various rooms. Therefore the users can be active in multiple numbers of rooms. They can also chat both privately as well as publicly. These can be performed in impressive tabbed interfaces. Radi: It is a visual design app that targets the web with both standard as well as human readable HTML, JavaScript code. There are built in tools for editing and creating graphics. The animations can be generated in the canvas output that works fine in all the modern browsers and even in handheld devices as well. For a more customized effect the filters (ready to use) as well as effects can be used by adding them in the developer’s codes. Roole: If you are looking for an alternative that is SASS or LESS (+stylus) inspired then check out Roole. It supports variables as well as conditional logic. The reason why developers should use it is because it enables to define the format used in the CSS. It is a well documented tool that works on both the server side and client side. As a developer if you are planning to use JavaScript as a programming language, these are some of the tools that you must be aware of. This would help you leverage the benefits of JavaScript development. We provide JavaScript web development services.

JavaScript is an aesthetic language used for web development. There are many special effects in this language that make user experience an improved and memorable one. So one thing should always be kept in central focus by the web developers- improvement of user experience. JavaScript offers many useful and clever ways in which a site may be improved from the perspective of user interface. Here are a few smart Javascript techniques which can help you improve UI performance.
1) insert AdjacentHTML instead of innerHTML- The extremely popular innerHTML has been transformed into a brand new avatar in the form of the optimized and fine grained version called insert AdjacentHTML. Since the position is specified, the element used upon is not re-parsed by this API; in fact extra serialization step is avoided which makes it much faster than the other manipulation. In approaches where the markup has to be appended continuously to a module or page this is very effective. Compared to innerHTML, insert AdjacentHTML is 100% faster.
2) requestAnimationFrame instead of setInterval- As compared to the conventional intervals and times, a more efficient as well as optimized approach is the use of requestAnimationFrame API while building animation based on JavaScript. The timer calculations are offloaded by this API to determine the timing of the upcoming UI/DOM style changes in the browser. It takes away from the responsibility of the developer to decide when the screen needs a repainting. Replacement with requestAnimationFrame will lead to smoother animations as well as saving of battery life in mobile devices if the content is viewed over there.
3) if-else instead of try-catch- Unforeseen runtime related errors and exceptions can be handled efficiently through the mechanism of try-catch. But a performance penalty is imposed by the blocks in JavaScript which is especially the case when used in recursive functions or iterations. On replacing try-catch with if-else conditions, each and every error handling will be taken care of; the resultant code will be much better as well as more efficient.
4. Improving startup performance- Try distinguishing between 'right after startup' and 'startup' and try to move to using 'right after startup' as much as possible. Design the UI in manner that as soon as the data changes it automatically updates. This result in saving of a lot of time and you will not have to wait for a long time so that everything may be ready. Some things are there which cannot be done right after startup; in short you will be able to perceive the startup time. To reduce the loading time you can combine CSS or Cascading Style Sheets. This will be especially perfect if many UI controls are in use. The loading time of almost 50 files can be reduced to near about 25% with the correct code combination. You can also try code minification; the benefits will be code-dependent- like 10-25%. To guarantee great startup one must-have is Lazy loading. To load a code of 10 MB, almost 10 seconds will be needed. But to showcase an initial view 100K is needed, if not more which means a loading time of 1 second. With lazy loading the 9 seconds may be deferred and scattered.
5) JQuery Autotab- It is often remarked that this feature is a must-have for all forms on internet. This may be a small thing but it provides a much better experience to the user when he or she is filling out forms and items, especially if there is the need to fill up things such as social security numbers, etc. If the form has jQuery then autotabs are added by the jQuery Autotab function.
There are so many options in JavaScript that can improve user experiences drastically like sliding top panel, social history, context highlighting web forms, magic zoom, password strength meter, etc. But while using them, in order to make them actually very effective, thoughtful implementation and restraint must be practiced. A perfect balance has to be struck. Use techniques that will actually be applicable as well as relevant; not just for the sake of using it. This would help you leverage the benefits of Javascript application development.
