Introduction

Web developers use JavaScript every day to bring the necessary functionality to the websites they create. jQuery is a special tool that provides powerful features and flexibility. jQuery is a JavaScript library that helps simplify and standardize the interaction between JavaScript code and HTML elements. JavaScript allows websites to be interactive and dynamic, and jQuery is a tool that helps simplify the process. We will dive into what this means, how it works, and why it is so useful.

jQuery usage by websites across the globe

JQuery is a fast, small JavaScript library contained in a single .js file. It provides many built-in functions, you can use them to complete various tasks easily and quickly. JQuery is a framework built using JavaScript functions. Therefore, you can use all the functions and other functions available in JavaScript.

You can use any JavaScript editor to write jQuery such as
❖ Notepad
❖ Visual Studio
❖ Eclipse
❖ Ultra edit

Both compressed and uncompressed versions of jQuery can be downloaded free from the internet. A compressed version should be used in the production environment whereas the uncompressed version is to be used in a development environment. Compressed version minimizes the library by eliminating extra white space, line feed and shortening the variable and function names. So the compressed version is not readable. An uncompressed library is readable, hence useful in debugging. Once the appropriate version is downloaded, it can be referenced in a file using a script tag.

jQuery can be used in two ways

● Local installation: download the jQuery library on your local machine and include it on your HTML code.
● CDN Based Version: you can include the jQuery library into your HTML code directly from a content delivery network. Google and Microsoft provide content delivery for the latest version.

When can be jQuery used?

➔ JQuery can be used to develop Ajax based applications.
➔ It can be used to make code simple, concise and reusable.
➔ It simplifies the process of traversing the HTML DOM tree.
➔ It can also handle events, perform animation and add ajax support in web applications.

10 Important Uses of JQuery

JQuery's API is well designed. Its functionality is so complete that the last few major versions of the library hardly added any new methods. JQuery plays very well with other code. It does not extend any built-in JavaScript objects, only adds a symbol to the global namespace. Some main uses of jQuery are explained in detail as follows:

1. Plugins

A plug-in is a piece of code written in a standard JavaScript file. These files provide useful jQuery methods that can be used with jQuery library methods. There are a large number of plug-ins on the web that allow web developers to create special effects simply and quickly

2. DOM Manipulation

jQuery makes it easy to select DOM elements, using a cross-browser open source selector engine called Sizzle to negotiate and modify them.

3. Animations and AJAX support

jQuery has a large number of built-in animation effects. It can also help you develop responsive and feature-rich sites using AJAX technology. Therefore, most web developers prefer to use jQuery to make web pages more exciting, interactive, cleaner, and more user-friendly

4. Cross-browser support

Currently, uses of jQuery are the most popular JavaScript library that works on all the browsers. It also supports CSS3 selectors and basic X Path syntax.

5. Write Less, Do More

JQuery handles many common tasks that require a lot of JavaScript code to complete, and packages them into methods that can be called with a single line of code. This makes 5 lines of jQuery equivalent to 25 lines of traditional JavaScript code. This means smaller files and faster web page loading.

6. Ease of learning

JQuery does not require any specific prerequisites to learn and is very simple because it is built on shorter code than JavaScript. Simple coding standards and coding syntax can greatly reduce the time required to develop and deploy a website. In addition, developers do not need any design skills or learning web design, because jQuery provides a wealth of built-in plug-ins.

7. Search engine optimized

Some jQuery effects are almost the same as Flash, but everything in jQuery is set to text. This makes jQuery smaller than Flash, and all search engine robots can read the content.

8. Easy integration with Visual Studio IDE

Visual Studio provides extensions to help integrate the jQuery library into the .Net framework project. The Visual Studio 2010 version supports the integration of the JQuery library into the .Net framework. The NuGet package extension for Visual Studio facilitates this integration. With the help of this integration, the IntelliSense function of visual studio is turned on. All jQuery methods of this function are automatically filled, and errors will be displayed where there is a syntax error.

9. Even when JavaScript is disabled, a jQuery element has still displayed

Some browsers have prerequisites to install adobe flash in order to render all content correctly. This is not the case with jQuery. Manipulating the HTML DOM has become the practice of developing and modifying web pages today. Therefore, content will be rendered even if JavaScript is disabled in the browser.

10. jQuery makes flash like animated applications

It takes time to learn Flash and years of experience to make animations in Flash, hence hiring Flash developers is not a cheap task. With jQuery, you only need to understand JavaScript and HTML to make animations. In addition, there are a large number of plugins to make this task easier.

Conclusion

jQuery is the best cross-browser JavaScript library, and its compilation aims to simplify HTML client-side scripting. Since jQuery is built on top of JavaScript, it provides all the features of JavaScript. From the above points we can say that jQuery is an enhanced version of JavaScript. 

JQuery has a lot of impressive effects, and web designers often use it to make their designs more cute and elegant. It minimizes the tasks of Web developers to a large extent by providing instantplug-ins.
