Yo ninjas, in this JavaScript tutorial, I just want to give you a brief introduction to the fantastic world of JavaScript libraries. A JavaScript library is essentially a chunk of code that someone else has written (normally for a specific purpose, but there are general purpose libraries too), that can greatly reduce your work load.

Any questions, fire away :).

  1. I have gone through all your videos and others as well and learned javascript but coming to a realtime development I m confused where to and how to apply … kindly do us a video for that .. I would be a great help

  2. Perhaps I'm mistaken… Knowing XML, I thought that <script "scripts/jquery-3.1.0.js"/><script "scripts/script.js" /> would work; but seemingly instead I have to write <script "scripts/jquery-3.1.0.js"></script>.

  3. You can grab an element by CSS selectors only with JS using document.querySelector("") or document.querySelectorAll("")
