Resolving setTimeout Inside for Loop with var in JavaScript: Closures and Scope | Interview Question

Показать описание

In this video, we'll dive deep into the common issue of using setTimeout inside a for loop with the var keyword in JavaScript. You'll learn why this problem occurs due to function scope, and we'll explore important concepts such as closures, block scope, and async functions. To resolve this issue, we'll demonstrate how to use the let keyword and an Immediately Invoked Function Expression (IIFE). By the end of this tutorial, you'll have a clear understanding of how to manage scope effectively in JavaScript.
