Was du lernst

Voraussetzungen

We expect that students have built web apps in the past and they are familiar with the pitfalls of callback-heavy code. There is no HTML or CSS in this class.

JavaScript Skills Required:

  • Using functions to return objects and other functions
  • Basic understanding of scope and closures
  • Reading and writing named and anonymous callbacks
  • Array methods like .forEach and .map

Other Requirements:

  • Ability to use GitHub to clone repos and checkout branches
  • Comfort with command line tools

Detaillierte technische Voraussetzungen

Was spricht für diesen Kurs?

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.
