Want to make your JavaScript functions faster? In this tutorial, you’ll learn how to memoize a function in JavaScript to cache previously computed results and improve performance — especially in recursive or heavy-calculation functions.

Memoization is a powerful technique in functional programming that helps avoid repeated work by storing results in memory. We’ll walk through simple examples like Fibonacci and real-world use cases where memoization makes a difference.

In this video, you’ll learn:
