jQuery is a Javascript open source library that simplifies web applications especially HTML. It is a compilation of many e-libraries that makes the navigation simple as well as easy to go. Its main object is to simplify document object model creations and its manipulation. It mainly works on XML and asynchronous event handling. jQuery is a set of Javascript e-libraries which does not require more effort for coding and it specifically simplifies HTML documents, Ajax animations and event handling with less coding requirement. So basically it is a very simple and easy way to work on web applications and event creations. When jQuery was not in existence most of the web users and developers used Javascript to create the web designs and framework for event handling, but it was a very time consuming script. Javascript was also very complicated in terms of web browsing, developing and coding too. So to simplify this process a group of web developers created a set of Javascript libraries which was more powerful and easy. So both are the same languages but it is a modified version of Javascript that simplifies HTML documents mainly. It focuses on working in less coding mainly. It is majorly optimized to work in a simplified way with a variety of web developers. It takes less time in animation and event handling for most of the web browsers.

Pros of jQuery:

Most of the Javascripts libraries work in a complex and large coding manner as compared to jQuery, that’s why this is the most used library in today’s time. Some projects need specific coding functions which are only available in traditional javascripts but jQuery can also make their styles scripted in this manner too. So it is a quick and smarter script as compared to others. Javascript still has difficulties to work on cross browsers but in the case of jQuery it can work with a variety of browsers in a simplified manner. So it is a less effort web tool which gives more results to give desired framework in a simple and light manner. As in Javascripts a lot of coding is required so jQuery can shorten those codes and lines in a simplified single line of coding wrap which makes the content more focused. That’s why it is the most popular yet most used library these days by many big names like Google, IBM, Microsoft and Netflix etc. In addition to simplifying the HTML codes and documents it also works on animations and graphic effects. DOM means document objects model, it can also manipulate these programs as well as it can handle AJAX and HTML events with ease and less coding. Beside this it can also manipulate CSS scripts and utilities with a variety of browsers including cross browsers too which can not be worked with other Javascripts. It helps to create dynamic web pages which provide a more powerful framework. These web pages are also helpful in making diverse web applications and their manipulation in scripts if required. In order to simplify the content first it separates HTML and Javascript libraries so that web developers can use these events separately and easily. With its shorthand functions it can make the content more clear and precise. Beside that it has the quality to add new methods and events to the previous elements, so it has adaption quality which makes it friendlier to users. It can also work with other Javascripts that were being used highly before it. Because of its key features it became highly popular among web users as it is now used by top of the websites and used by more than 74% of users worldwide after its launch in 2006. By its plug-in feature it became more accessible and extensible for manipulating events. As it has an open source engine called Sizzle it enhances the work efficiency with different varieties of web browsers. It can control asynchronous processing of lines and codes and also provides detection of features. The most important feature of jQuery is it can cope up with both modern browsers as well as old browsers which make it compatible to all the browsers. So it is a wrap up of many Javascript files which includes HTML, DOM, AJAX events and their files with manipulation and scripting of different files and their events in a less coding service for all the different web developers and browsers.

Cons of jQuery:

There are also some drawbacks of this most used library along with so many qualities as it contains all its files and components as a single file so when the user downloads it it comes as a huge e library with a very long uncompressed file of kilobytes. As it takes a lot of time plus it occupies a large space too. One more is that some new and modern browsers can also do the same work like jQuery now and they also do not take too much time in this. So its DOM manipulating feature is now accessible and much quicker with modern browsers help. With that its complex parts are also hidden in its abstraction so creates problems sometimes for web users and developers. So these are some features of jQuery with some pros and cons included for the knowledge of tech users or start ups who want to know about Javascript and its most popular set of e- libraries named jQuery.
