front-end development

Being a hugely popular client-side scripting language, JavaScript doesn't need any introduction. And also being used as part of browsers, JavaScript also controls the web browsers, effectuates user interaction, facilitates asynchronous communication, and delivers customized prepared to users. So most web designers use JavaScript to reduce the time and effort necessary for building large or complex websites. The web developers also have option to use several JavaScript frameworks to effectuate and speedup web design.

JQuery is a widely used cross-platform JavaScript library. Despite being open source, jQuery is straightforward to utilize, fast and concise. The API provide by jQuery works seamlessly on major internet browsers. Also, the feature-rich JavaScript library makes it much easier for web-developers to govern HTML documents, handle events, create animations, select DOM elements, and create AJAX application. At the same time, jQuery could also be used for making a selection of plug-ins by taking the best-selling JavaScript library.

Thus, the modern web designers have substitute for use JavaScript and jQuery either independently or side by side. However, additionally it is very important to the programmers to know a number of the major differences between JavaScript and jQuery.

4 Important Differences between JavaScript and jQuery

1) Programming Language and Library

Like a dynamic programming language, JavaScript supports object-oriented, structured, functional and imperative programming styles. The first-class functions and dynamic typing also make JavaScript categorized being a prototype-based scripting language. On the other hand, jQuery is really a JavaScript library. The framework makes it much easier for developers to accomplish a number of common web tasks like HTML document manipulation, event handling, animation, DOM element selection and AJAX application development.

2) Scripting Time

Whenever a web master decides to use straight JavaScript, he must write additional code to perform several tasks. He further has to put extra time and for debugging and fixing browser compatibility issues. But jQuery allows developers to benefit from existing scripting. For them to utilize the scripting existing in jQuery to accomplish a number of web tasks without writing longer lines of code. Thus, jQuery makes it easier for web programmers to save lots of enough time and efforts required for building modern websites and internet applications.

3) Simplification of Client-Side Scripting

As a client-side scripting language, JavaScript makes it much simpler for developers to effectuate user interaction and deliver customized happy to users. However the developers must write longer lines of code to write down an internet application in straight JavaScript. So web designers often use JavaScript development frameworks to perform the scripting functions easily and quickly. Being a cross-platform JavaScript library, jQuery includes features to do the normal scripting functionalities. So developers may use the library to simplify the client-side scripting of HTML. The plug-ins, widgets and UIs given by the framework help web programmers to drastically reduce development time.

4) Performance

Both JavaScript and jQuery run quite faster on the latest browsers and computers. But the speed of both JavaScript and jQuery is suffering from utilization of older browsers. As JavaScript have access to the DOM quicker than jQuery, the programmers can simply curtail the overheads linked to the library. However, jQuery makes it easier for developers to build high-performing websites and internet application by availing functionality independent of browsers.
