Which is better to use jQuery or JavaScript?

Pure JavaScript can be faster for DOM selection/manipulation than jQuery as JavaScript is directly processed by the browser and it curtails the overhead which JQuery actually has. JQuery is also fast with modern browsers and modern computers. JQuery has to be converted into JavaScript to make it run in a browser.

Why should we use jQuery instead of plain JavaScript?

jQuery helps in CSS manipulation, making AJAX requests, handling JSON data received from the server, and also helps in adding animation effects like hide, show etc to the components. jQuery simplifies a lot of things. It’s easier to implement some things using jQuery than vanilla JS. Have a look at this example.

Is jQuery faster?

Is jQuery is an advanced version of JavaScript?

Why is WebAssembly faster than JavaScript?

WebAssembly can be faster than JavaScript because it’s the result of ahead-of-time compilation of some high-level programming language, such as C++ or Rust. JavaScript, on the other hand, is parsed, compiled, and optimized at runtime. All these operations have overhead, which is avoided with WebAssembly.
