Course Description

We all visit dozens of websites every single day, but did you realize that virtually all e-commerce websites and social networks implement Promises, JavaScript’s built in tool for handling actions that communicate with other networks?

In this course, JavaScript promises, you’ll learn all about these highly efficient tools for making websites efficiently and easily do commonly needed tasks such as

  • Logging users in and out

  • Fulfilling orders

  • Saving payment details

  • Sending instant messages

If you can understand why the above tasks are critical for any eCommerce application, you can easily see how learning promises, which are used to do all these things, is valuable!

We’ve tried to pack as much information on Promises into one short course. We really took out everything except what you absolutely need to know!

Here’s a small fraction of what you’ll learn:

  • What promises are

  • How and where to use promises

  • JavaScript code required to implement and consume promises

  • Understanding of the promise library ecosystem

  • Promise methods catch and then

  • How to implement the Promise spec

  • How to troubleshoot promises

  • How to chain and combine promises

  • How to use promises with async / await

So, why hesitate? Sign up for this course today! And in less than 24 hours, you can be a more efficient and skilled web developer. Improve your promise skills to unlock these advantages in your career:

· More esteem from team leads and coworkers, stemming from ability to confidently discuss promises and make recommendations
