JavaScript Promises

About this Course

Learn how to simplify asynchronous work with Native JavaScript Promises!

[

Every web developer needs to be able to work with asynchronous code. Network requests, browser events, web workers and just about every else about the web happens asynchronously.

JavaScript developers normally rely on callbacks to execute async code, but Native JavaScript Promises offer a much easier solution. With Promises, error handling is streamlined and it becomes possible to flexibly chain lots of asynchronous work without creating a tangled mess of callbacks.
