Loops are one of the core building blocks of programming. In this video, I start with a simple JavaScript program that doesn’t use loops and show why that approach quickly becomes a problem. Then I explain what loops are, why they’re useful, and how the while loop works in practice. We finish the video with a program where we make a robot take steps. You’ll learn: - what problems arise when you don’t use loops - how a while loop works step by step - how the loop condition controls repetition - what an infinite loop is - how to force-break a loop - how to skip a loop iteration If you want to build a strong foundation in programming, this lesson will help you understand one of the most important control structures. 📌 Chapters: 00:00 Intro 00:05 A program without a loop 01:40 What is a loop 02:06 While loop 08:14 Comparing programs 08:56 Robot example 12:59 Outro
