Key Differences Between JavaScript and jQuery

differences between Javascript and jQuery

JavaScript is an interpreted, dynamic programming language. Its name is similar to the Java programming language but it has nothing to do with it.  It is a scripting language and is used for appealing UI, user interactions and for controlling the document content that is displayed to the viewers.

On the other hand, jQuery is not a programming language but is a cross-platform JavaScript library. It is a fast and concise library that simplifies the HTML document traversing, animating, event handling, and Ajax interactions for rapid web development. Today, we will look at the key differences between Javascript and jQuery.

jQuery is nothing but a library of JavaScript. It can’t replace JavaScript as all the jQuery code is Javascript. They both are not two different programming languages but both are actually JavaScript. jQuery is just optimized to do the common scripting functions with less number of lines of code.
