A few of the Differences Between JQuery and JavaScript


As a very popular client-side scripting terminology, JavaScript does not need any introduction. In addition to being used as part of web browsers, JavaScript also regulates the web browsers, effectuates user interaction, facilitates asynchronous communication, and provides custom-made content to users. So 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 simple to use, fast and concise. The API provide by jQuery works seamlessly on major web browsers. Also, the feature rich JavaScript library makes it easier for web designers to manipulate HTML documents, manage events, create animations, select DOM elements, and build AJAX application. At the same time, jQuery can even be used for creating a variety of plug-ins through benefits of the JavaScript catalogue.

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

4 Important Differences between JavaScript and jQuery

1) Development Language and Library

As a dynamic programming language, JavaScript supports object-oriented, organised, functional and imperative programming styles. The first-class functions and dynamic typing also make JavaScript categorized as a prototype-based scripting language. On the other hands, jQuery is a JavaScript library. The framework makes it easier for programmers to accomplish a amount of common web tasks like HTML document treatment, event handling, animation, DOM aspect selection and AJAX application development.

2) Scripting Moment

When a web developer decides to use straight JavaScript, he’s to write additional code to accomplish several tasks. He further has to put extra time and effort for debugging and fixing browser suitability 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 program code. Thus, jQuery helps to ensure profound results for web programmers in order to save the time and efforts necessary 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 customer interaction and deliver custom-made content to users. But the developers have to create longer lines of 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 perform 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 drastically reduce development time.

4) Performance

Both JavaScript and jQuery run quite faster on the latest web browsers and computers. But the speed of both JavaScript and jQuery is influenced by use of older internet browsers. As JavaScript can access the DOM faster than jQuery, the programmers can certainly curtail the overheads linked to the library. However, jQuery makes it easier for developers to build high-performing websites and internet application by availing features independent of web browsers.
