jQuery vs. JavaScript

What is jQuery

A free and open-source javascript library which is basically used for designing, traversing and manipulating the HTML DOM. A DOM is a tree-like structure used to represent the elements of a webpage. jQuery helps the designer to use javascript code easily for their websites. The advanced approach to jQuery enables to create powerful dynamic webpages and web applications. The syntax of jQuery is designed to make things easy, such as:

  • Navigation of a document
  • Selection of DOM elements
  • Creating animations
  • Handling events
  • Developing Ajax applications.

jQuery is one of the widely used javascript library among all other libraries holding the following core features:

  1. DOM elements selection
  2. Traversal and manipulation which is enabled by Sizzle(the selector engine)
  3. Creating a new programming style
  4. Fusing DOM data structures and algorithms

On the other hand, jQuery allows developers to create plug-ins on top of the JavaScript library. Developers can even create abstractions for low-level interaction and animations, too.

It is required to include the URL of the jQuery library in the header of the page. JavaScript is supportable on every browser. Any additional plugin need not to be included.
It depends on the JavaScript as it is a library of js. jQuery is a part of javascript. Thus, the js code may or may not depend on jQuery.
It contains only a few lines of code. The code can be complicated, as well as long.
It is quite an easy, simple, and fast approach. It is a weakly typed programming approach.
jQuery is an optimized technique for web designing. JavaScript is one of the popular web designing programming languages for developers that introduced jQuery.
jQuery creates DOM faster. JavaScript is slow in creating DOM.
