17 Useful Library and Components for Javascript Developers

JavaScript is a popular way of enabling programmatic access to computational objects within a host environment with the use of scripting language. It is currently the most popular programming language in the web. The objective of the functional programming language is to enhance user interface and to provide dynamic and interactive websites. The programmers can apply some scripting modules from different JavaScript libraries or toolkits to create awesome and effective screen-casts.

The following is a JavaScript developer center that includes some JavaScript libraries that offer different modules like Core, AJAX, Events, Load, CSS and many more.  Whether the programmers want to provide enhanced multiple file upload methods, creating standard based web forms, or devise mouse gesture, they have many options of JavaScript libraries. Likewise, creating interactive maps, images and image effects, multiple types of charts, and graphs is highly possible with charting or image development toolkits.


DOMAssistant is a modular lightweight JavaScript library, with CSS selectors, event handling, AJAX and complete Unicode support. It consists of 6 individual modules (Core, AJAX, Content, CSS, Events, and Load), but only the core DOMAssistant module is required. All other modules are optional, and you can choose to only use the ones you find necessary in your application.

ValidForm Builder  is a open source PHP and JavaScript library that simplifies creation of standards based web forms. It also helps you to validate form fields, both on client and server side. It requires PHP 5+ and jQuery, and works in all major browsers (Internet Explorer 6+, Firefox 2+, Opera 9+, Safari 2+, Chrome).


Uki is a simple JavaScript user interface toolkit for creating desktop-like web applications with few lines of code. The toolkit is fast. It uses progressive rendering, can render 30k+ lists & tables very quickly (which would normally take minutes in IE).


Moousture  is a JavaScript mouse gesture library, built with MooTools. It simply checks the mouse movements & catches them if they follow any given route.


Grafico is an open source JavaScript charting library built with Raphaël & Prototype.js. It is possible to create multiple types of charts like line, area, bar & stacked charts, sparklines and more.

Alloy UI  is a JavaScript UI library, a CSS framework, a set of HTML recipes and a taglib library, all combined to empower developers across multi-skilled teams deliver rich and dynamic applications.


Sexy.js  is a lightweight (<1kb compressed) JavaScript library that provides enhanced sequential Ajax (Sajax) functionality. The library is chainable, enables you to manage script dependencies and write prettier code.


Polymaps  is a free JavaScript library for creating dynamic and interactive maps. Besides the usual cartography from OpenStreetMap, CloudMade, Bing, etc., it works with image-based and vector-tiled maps by providing a quick display of multi-zoom datasets over maps, and supports a variety of visual presentations.

By default, the library helps loading all scripts in parallel (it is possible to define priorities) which is a great speed improvement that we usually see with asynchronous scripts.


canvasXpress  is a free JavaScript graphing library based on the <canvas> tag of HTML5. It supports multiple graph types including bar, line, dotplots, area, stacked, heatmaps, pie charts and more.

The JavaScript developer center is a comprehensive source of comprehensive frameworks and libraries that help the programmers enhance the user interface on the websites. The toolkits and libraries are functional in assisting the programmers with improved JavaScript programming functionality.

Various server-side JavaScript platforms allow the users to create different platforms for different purposes. Now the question is to what extent the libraries or toolkits take different browsers into account? Can the toolkits be used for different host environments?
