JavaScript Recursion Visualization
Understand JavaScript recursion by exploring the call stack and function invocation costs. Learn how multiple execution contexts operate during recursion, recognize potential stack overflow errors, and discover optimization strategies like trampoline or tail-call techniques. This lesson helps you visualize recursion to deepen your functional programming skills.
We'll cover the following...
Background
We just saw a lot of function invocations. Go ahead and look at the cost of function invocation. Every function invocation is costly for a program. In the example of recursive functions, we can use neater code, but it comes at a cost. Let’s take a look at it in greater detail.
Introduction to call stack
All programs maintain a “call stack” where every invocation of a function pushes them onto the stack and then removes them when the function returns. Every function invocation adds an ...
