Function Execution Context in JavaScript
Learn how the JavaScript engine creates a new function execution context when a function is called. We walk through what happens step by step when you invoke a function, including how variables are handled inside it.
This lesson shows you the difference between function declarations and expressions during execution, and how execution contexts are set up and later removed. By the end, you will better understand how JavaScript runs your function code behind the scenes.
