Why jQuery is important???? What is its uses ???

Question

I am little bit confused over learning jQuery....
Didn't know where it is used????
#jQuery

Answer 1

According to the jQuery website "write less, do more"
That is pretty self explanatory, but it means you can do more with less code
The soloLearn course shows you how jQuery can minimalise code in JavaScript

JavaScript

var el = document.getElementById("start");
el.innerHTML = "Go";

jQuery

$("#start").html("Go");

so the code you see in jQuery does the exact same thing that ordinary JavaScript does.
