As a very popular client-side scripting terminology, JavaScript does not need any introduction. Not only is it used as part of web browsers, JavaScript also regulates the web browsers, effectuates user interaction, facilitates asynchronous communication, and gives personalized content to users. Therefore most web developers use JavaScript to reduce the time and effort required for building large or complex websites. The web developers also have option to use several JavaScript frameworks to effectuate and speedup web development.

JQuery is a widely used cross-platform JavaScript library. Regardless of being open source, jQuery is not hard to use, fast and concise. The API provide by jQuery works seamlessly on major web browsers. Also, the feature-laden JavaScript library makes it easier for web designers to manipulate HTML documents, handle events, create animations, select DOM elements, and build AJAX application. At the same time, jQuery can be used for creating a variety of plug-ins if you take features of the JavaScript library.

Thus, the modern web developers have option to use JavaScript and jQuery either independently or aspect by side. However, it is also necessary for the programmers to understand a few of the major variations between JavaScript and jQuery.

4 Important Differences between JavaScript and jQuery

1) Programming Language and Library

As a dynamic programming language, JavaScript supports object-oriented, structured, functional and imperative encoding styles. The first-class functions and dynamic typing also make JavaScript categorized as a prototype-based scripting terminology. On the other hand, jQuery is a JavaScript library. The framework makes it easier for designers to accomplish a quantity of common web duties like HTML document adjustment, event handling, animation, DEM component selection and AJAX application development.

2) Scripting Time

When a web developer decides to use straight JavaScript, he’s to write additional code to achieve several tasks. He further has to put extra time and effort for debugging and fixing browser compatibility issues. But jQuery allows developers to consider good thing about existing scripting. So they can use the scripting existing in jQuery to accomplish several of web tasks without writing longer lines of code. Thus, jQuery helps to ensure profound results for web programmers to save the time and efforts required for building modern websites and internet applications.

3) Simplification of Client-Side Scripting

Being a client-side scripting language, JavaScript makes it easier for developers to effectuate consumer interaction and deliver custom-made content to users. But the developers have to publish longer lines of computer code to write a web application in straight JavaScript. So web-developers often use JavaScript development frameworks to accomplish the scripting functions easily and quickly. As a cross-platform JavaScript collection, jQuery comes with features to execute the common scripting functionalities. So developers can use the library to simplify the client-side scripting of HTML. The plugins, widgets and UIs provided by the framework help web programmers to significantly reduce development time.

4) Performance

Both JavaScript and jQuery run quite faster on the latest web browsers and computers. Nevertheless the speed of both JavaScript and jQuery is influenced by use of older web browsers. As JavaScript can entry the DOM faster than jQuery, the programmers can certainly curtail the overheads associated with the library. However, jQuery helps to ensure profound results for developers to build high-performing websites and internet application by availing efficiency independent of web web browsers.

On the whole, JavaScript is a dynamic and feature-rich programming language, whereas jQuery is a collection of JavaScript code. The proficient JavaScript developers may easily use jQuery to achieve a number of tasks without writing longer lines of computer code. Nevertheless , they can still use jQuery without being proficient in the popular client-side scripting language. Of which is why; the designers need to choose JavaScript or jQuery in accordance with specific needs of the project.
