JavaScript the Hard Parts: Callbacks & Higher Order Functions

Join us for a live, interactive workshop where we’ll dive deep into the callbacks and the functional programming side of JavaScript.
​
What you’ll learn:

  • How to recreate core functions like map, reduce, and filter from scratch
  • How to use higher-order functions to simplify complex code and avoid repetition
  • Techniques for diagramming and visualizing callback flows and higher order functions

Guided by one of our expert Codesmith instructors, this hands-on session will break down callbacks and higher order functions step-by-step. If you’re ready to unlock the full potential of functional programming in JavaScript and write code that’s both efficient and expressive, this workshop is for you!

‍

Is this workshop right for you?‍

To get the most out of this workshop, we recommend getting started on our free learning platform CSX and working up to the Callbacks unit before the workshop.
