Join us online to master JavaScript closures and scope!

This workshop will be a combination of live interactive lecture and pair programming through challenges. You will go under-the-hood of JavaScript, so you can confidently tackle new problems and work through blocks.

During this workshop we will cover:

Understand how closure works under the hood (one of the most misunderstood but most powerful features of JavaScript)

Understand core JS runtime features - execution context, JavaScript execution model and the variable environment

Be able to wield, optimize and debug popular pro utility functions like once and memoize

Be able to implement the module pattern - one of the cleanest and most resilient design patterns in JavaScript

Price: Always free!
