jQuery
jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, and animation much simpler with an easy-to-use API that works across a multitude of browsers.
Hello, World!
$("body").append("Hello, World!");How I used jQuery
I did not. It’s outdated and does not bring any value to modern web development. However, I consider jQuery an important part of web history, I’m fully proficient in it, and I’m grateful to it for essentially laying the foundations for modern JavaScript and web development. Without jQuery, there would be no React, Vue, Angular, and other frameworks that are standard today.
