In the real world, everything doesn't happen one after the other. You might be stuck with a data fetch that takes a couple 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.
What will you learn in this course?
2. You'll learn the ins and outs of one of the major topics that can land you a job or a promotion
3. You’ll know how to apply those concepts in your projects and create clean code that runs faster than your peers.
5. You'll learn about callbacks and how you've probably been using them in your daily programming already
6. You'll learn about the pros and cons of callbacks, callback hell and why we need a replacement
7. You'll learn about promises, an ES6 update, and how they replaced callbacks
8. You'll learn about handling errors in promises
9. You'll learn about making promises prettier with Async Await, an ES7 update
10. You'll learn about handling errors in async await
11. You'll learn how to apply what you learn in 3 real world mini projects
12. You'll learn one of the most complex topics of programming with easy to understand examples and hands-on explanations
Who is this course for?
2. Web developers who'd like to pad their resume and get that promotion they've always wanted.
3. Web developers who'd like to add "Asynchronous programming" to their resume and stand out in your job interviews.
5. Fledgling developers who'd like to learn how real world programming works
6. Front end developers who are working with frameworks like Angular, React, Vue or Svelte and would like to apply Asynchronous programming concepts in their projects.
How is this course designed:
Module 3 : Promises - In this module, let's take a detailed look at the ES6 update Promises, why they were needed and how they pretty much replaced calbacks. Let's also look at how we can get their resolutions and errors and display them, creating promise chains, promisification and error handling in promises. We'll end this module by creating the same mini project, but this time with promises and comparing them to callbacks.
Module 4: Async Await - In this module, we'll look at Async Await, an ES7 update, and how they've made promises look pretty. We'll also look at resolving multiple promises at the same time using Async Await and error handling. We'll end this module with a mini project as well.
