Overview What You Will Learn Curriculum Instructor

Course Overview

Would you like to take your JavaScript knowledge to the next level? Would you like to become a master JavaScript programmer by mastering one of the most complex, but very important aspects of web development? Asynchronous programming is real-world programming, and if you master it, you'll certainly stand out from your competitors!

JavaScript wasn't designed to be an Asynchronous language, but with just the right tweaks, you can make it Asynchronous. 

In the real world, everything doesn't happen one after the other. You might be stuck with a data fetch that takes a couple of seconds to execute. You can't make the rest of your code wait for it to finish executing though. Asynchronous code helps you manage everything seamlessly while making sure that the data you're waiting for (in our example) is used in your code ONLY after it has been completely fetched. Sounds like magic, doesn't it? 

But it also sounds too complicated.

Don't worry.

You'll learn every single concept of Asynchronous JavaScript with easy-to-understand over-the-shoulder examples and detailed, but interesting explanations.

You'll learn all about event loops and how JavaScript works behind the screen and how it executes Asynchronous code, about callbacks and their drawbacks, how promises replaced them and how Async Await made promises prettier. You'll apply all of these in 3 real-world mini projects as well.

So, if you'd like to delve deep into the exciting world of Asynchronous programming, especially with JavaScript as your language of choice, this course is perfect for you.
