What Is jQuery?

jQuery is a JavaScript framework that makes traversing and manipulating the HTML DOM tree, as well as event handling, CSS animation, and Ajax, more easier. It's open-source software that's free and uses the liberal MIT License. jQuery is utilized by 73 percent of the 10 million most popular websites as of May 2019. According to web analysis, it is by far the most extensively used JavaScript library, with at least 3 to 4 times the usage of any other JavaScript library.

The syntax of jQuery is intended to make navigating a document, selecting DOM components, creating animations, handling events, and developing Ajax apps easier. Developers can use jQuery to build plug-ins that run on top of the JavaScript library. Developers can use this to create abstractions for low-level interaction and animation, complex effects, and themeable widgets at a high level. The jQuery library's modular design enables the building of sophisticated dynamic web pages and Web apps.

The selector engine enabled by jQuery's fundamental features—DOM element selects, traversal, and manipulation—created a new "programming style" that fused algorithms and DOM data structures. This design philosophy inspired the development of subsequent JavaScript frameworks such as YUI v3 and Dojo, eventually leading to the introduction of the Selectors API. Later, in an heir of jQuery, the D3.js framework, this style was extended with a deeper algorithm-data fusion.

jQuery is included in Microsoft's and Nokia's platforms. It's included with Visual Studio for usage with Microsoft's ASP.NET AJAX and ASP.NET MVC frameworks, and Nokia's Web Run-Time widget development platform.

Main Features of jQuery

  • DOM element selections using Sizzle, a multi-browser open source selector engine that leverages elements' names and characteristics, such as id and class, as criteria to choose nodes in the DOM.
  • Events
  • Animations and effects
  • To control asynchronous processing, use the Ajax Deferred and Promise objects.
  • Parsing JSON
  • Plug-ins provide extensibility.
  • Features detection, for example, is an example of a utility.
  • jQuery.inArray() and jQuery.each() are examples of compatibility techniques that are natively present in contemporary browsers but require fallbacks for older browsers ().
  • Cross-browser compatibility

 

Advantages of jQuery

Advantages

Usability: JQuery is a lot easier to use than normal javascript and other javascript libraries, which is pretty much the main benefit of using it. Aside from the simplified syntax, achieving the same feature needs far less lines of code.

Large library: In comparison to other Javascript libraries, JQuery's large library allows you to conduct a lot more functions.

Opensource community that is strong: JQuery has a devoted following who commit their time to developing and improving its capabilities, despite the fact that it is still relatively new. As a result, you may download hundreds of pre-written plugins to help you speed up your development process right away. The script's efficiency and security are two additional benefits.

Excellent tutorials and documentation: JQuery's website provides extensive documentation and tutorials that may help even the most inexperienced programmer get started with this framework.

Ajax support: JQuery's Ajax support makes it simple to create Ajax templates. Ajax allows for a cleaner interface by allowing actions to be done on websites without requiring the entire page to be reloaded. Above the fold on HowToRefinanceYourMortgage.net, you can see a pretty but simple example of this.

 

Disadvantages

It is possible that the functionality is restricted: While JQuery has a large library, depending on how much customisation you need on your website, its capability may be limited, forcing you to use raw javascript in some circumstances.

javascript file from JQuery is required: While the JQuery javascript file is modest (25-100KB depending on server), it still puts a load on the client computer and possibly your web server if you plan to host the JQuery script yourself.
