How can you actually understand JavaScript in such a way that you wont have to go and revise and revise again?

Question

What are the uses of AngularJs, React.Js, and Jquery?
Are they equivalent to the main javascript or how?
Where can one learn it and understand very well?
Thanks.

Answer 1

1. Angular JS, React.JS and jQuery are all JavaScript libraries, which means that it has code snippets which make it shorter and easier to use in websites.

2. They all make the JavaScript code shorter. So they all are JavaScript except they have functions stored in variables ( something like that)

3. Sololearn has jQuery course and is also adding ReactJS course. You can also refer to https://www.w3schools.com for more courses

Answer 2

We learn javacript by learning and use it to make web site .
