Write less, do more: jQuery philosophy

As you may know, jQuery is a free open-source library used to design the HTML DOM, a tree-like structure built from elements. Being the most popular library used in making the HTML DOM, jQuery helps developers to use Javascript and makes writing codes much easier. The syntax of jQuery is designed to make things easily understandable.

1. Navigation of a document

2. Selection of elements

3. Creating animations

4. Handling events

5. Developing Ajax applications

jQuery is a widely used Javascript library among all the libraries and holds the following features:

jQuery

Selecting DOM elements, traversal and manipulation enabled by Sizzle (selector engine), creating a new programming style, fusing DOM data structures and algorithms.

  • jQuery is a javascript library whereas Javascript is a dynamic programming language.

  • In jQuery, the user has to write the entire jQuery code, which is less time consuming but in Javascript, the user needs to write the complete Javascript code, which takes a lot of time.

  • In jQuery, the URL is required in the header of the HTML page for running the code on the browser whereas Javascript is supported by all browsers. No additional URLs are not required in it.

Example:-

Example:- <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jQuery-3.2.1.min.js"></script >

This script is used in jQuery.

jQuery depends on Javascript because it is the library of Javascript. Javascript is an independent web-development programming language and it is not dependent on jQuery.

jQuery is simple, fast and easy while Javascript is a weakly typed programming approach.

jQuery is also called optimized technology for designing web pages whereas JavaScript is one of the popular scripting languages for developers to design web pages.

jQuery

jQuery is used for creating DOM (document object model) faster while JavaScript is slow in creating DOM.

Javascript can be faster for DOM selection than jQuery. In jQuery we can also add animations, effects and more properties with ease.

jQuery is lightweight but Javascript is a language and hence it is heavier than jQuery.

Users can perform animations on web pages in JavaScript by using many lines of code because these are done by manipulating the HTML page while in jQuery one can add any animations easily with simple, small lines of code.

jQuery works on the philosophy “Write less, do more.” It already has a pre inbuilt library so less of writing codes. 

A Javascript code is written in the following way:

document.getElementsByClassName("simple-li");

A jQuery code is:

$('simple-li')

Conclusion:

While Javascript is faster than jQuery for access to DOM, it is also complex. jQuery is used for more applications, especially for rapid development apart from taking care of browser errors.
