vanilla javascript vs jquery [closed]

Question

I am having trouble grasping the difference between the two. I tried downloading the library and there was no code. I am trying to build a basic slider along with other basic functions I have built in jQuery. Any help, tutorials, plugins and information would be very helpful!

Answer 1

"Vanilla JS" refers to plain, unmodified JavaScript.

document.getElementById('myelement').innerHTML = "I was written with JavaScript!";

jQuery is a collection of functions and stuff that are intended to make it easier to write JavaScript (although personally I feel it makes it more like spaghetti)

$("#myelement").html("I was written with jQuery!");

Since jQuery is just a bunch of JavaScript, plain JavaScript is ALWAYS faster to run. It may be harder to write because you have to actually think about what you're doing, but it will run faster than the same thing in jQuery.

For a comparison of the two code samples above, see this JSPerf
