JavaScript is a very popular language now. And in today's world, if you want to stand out from everyone who's learning web development, you have to be the best.

Having a core, solid understanding of JavaScript would enable you to become a much better developer and you'll be friendly working with JavaScript.

This course aims to cover theoretical parts of JavaScript (there's another course for advanced practical JavaScript, so make sure to check that out after this one) where we would go over things that power JavaScript but aren't really things which you'll usually interact on with day-to-day basis.

  2. DOM

  3. ECMAScript standard

  4. Microtask queue

  5. Task queue

  6. rAF queue

And more! This course is regularly updated to include more advanced things I discover and could condense into a sizable chunk of knowledge, so stay tuned!
