  • Firstly, it helps with HTML event handling, document browsing.
  • It might be one of the reasons why JavaScript performs very poorly when it comes to sophisticated tasks.
  • However, when the logic becomes more sophisticated, jQuery outperforms JavaScript.

Both are fantastic web development languages that meet our requirements to a large extent. Simplilearn’s Java Certification training course is perfect for anyone who wants to master web application https://globalcloudteam.com/ development for almost every computing platform.

Handling user events and API calls

A. JavaScript is an independent language and can exist on its own. Whereas, iQuery is a JavaScript library and is still dependent on JavaScript. It has to be converted to JavaScript internally for the browser’s in-built JavaScript engine to run and decipher it.

Plain JavaScript is faster than jQuery but when you start writing complex logical codes with JavaScript and jQuery, JQuery always outperforms. Furthermore, there could be an underperformance in the coding writing by the developers in JavaScript when the logic is complex as it gets lengthy. In such a scenario, incorporating jQuery will make the coding writing easier and readable boosting the performance of the developers.

JavaScript Examples vs. jQuery Examples

JQuery has been optimized to perform many functions of scripting and it can perform these functions with the help of just a few lines of code. Developer-Friendly – jQuery is developed to make JavaScript more developer-friendly so that web developers use JavaScript more regularly and extensive rather than just for the necessities. When it takes a lot of time and space to write codes in JavaScript to achieve a purpose, jQuery will do it with minimal lines of codes and hence, the coding will be clean, readable, and efficient. There are certain in-built library functions in jQuery whose scripts already exist in the library.
