What is jQuery?

In simple terms, jQuery is a Library. Didn’t get it? Ok, let’s understand from the beginning.

In Web development, webpages are designed using HTML, CSS, JavaScript, etc. HTML is used to develop static webpages; CSS adds design to pages, and JavaScript makes webpages dynamic, i.e. it allows to reflect changes dynamically.

It has an easy-to-use API that works across cross-browsers. It has changed the way of writing JavaScript to a minimalistic way with its superior features. We will have a better understanding of all this in the following part.

Understanding jQuery

It is something that greatly simplifies JavaScript programming. It makes it much easier to use JavaScript on webpages. See, the catch here is those things which are achieved by using JavaScript; we can achieve the same by using jQuery, but in a very simplified manner, with very little complexity. Technically, jQuery is a fast and concise JavaScript library created by an American Software engineer and entrepreneur John Resig in 2006.

How does jQuery make working so easy?

It was created with a nice moto “Write less and do more”. jQuery’s entire functionality revolves around simplifying every line of code.

What can you do with jQuery?

Using jQuery, we can create animations, develop Ajax-based applications. It also provides capabilities for developers to create plug-ins on top of the JavaScript library, which enables developers to create abstractions for low-level interaction and animation, advanced effects, and high-level, themeable widgets. The modular approach to the use of the jQuery library allows the creation of powerful dynamic web pages and Web applications. These are some of the examples of what we can do using jQuery.

Advantages
It is easy to use as compared to standard JavaScript and other libraries.
It has a lot of functionality that is readily available.
It has already available plugins, which make developers’ life easy.
Ajax is a very useful technique for creating faster, better, more interactive web applications, and it has Ajax support.
It has cross-browser support.
It is a very lightweight library with a size of about only 19KB.
Required Skills

The pre-requisites required to learn jQuery are HTML, CSS, and JavaScript. One should understand what DOM is, how DOM is manipulated, and how CSS is applied. Overall a basic understanding of front-end development along with these skills is required.

Why should we use jQuery?
Web developers manipulate the DOM to make a web page interactive, making it extremely easy to manipulate DOM. DOM is a tree structure of HTML elements.
It is a free and open-source library. Its community of contributors is more diverse and bigger than any other JavaScript library.
It has detailed and comprehensive documentation, which gets better every day.
It has more than 1000 plugins that are available for free, and they can be easily included in the projects.
It has cross-browser support, i.e. it supports almost all commonly used web browsers.

All these reasons answer why one should be using it.

Scope

It is one of the most popular JavaScript libraries. According to statistics, It is used by around 97% of all websites which use JavaScript. It is still there, but due to some requirements, some developers are switching to other preferences. One of the problems with jQuery is that the processing time it takes to execute is more in some cases, and that makes websites slow. Still, there are many options available as of now in 2019, but it is not going anywhere soon.

Why do we need jQuery?

It wraps the many lines of JavaScript code into a single line of code and provides the same functionality. It simplifies a lot of the complicated things from JavaScript, like DOM manipulation and AJAX calls. It makes event handling, animation much simpler. It has an easy-to-use API that runs across a large number of browsers. JavaScript becomes so easy and simple when we use jQuery. Basically, It makes development faster and reduces time and effort.

Who is the right audience for learning jQuery technologies?

Anyone with basic knowledge of programming and web technologies can learn jQuery. Any software engineer or developer can learn jQuery. If you want to excel as a front-end developer, then you can learn jQuery.

How will this technology help you in career growth?

If you are a front-end developer, then jQuery will add value to your profile. It offers a great deal of flexibility and power to web designers. It is widely used, is lightweight and clean, and open source. Having this skill will be an advantage to web developers in career growth.

Conclusion

It is worth the effort, money, and time. This library can offer stunning effects on the website. With a little coding, It will be a big part of web development. It has all the tools needed to build a website that is interactive and highly engaging. Overall, it is a game-changing technology.y
