For Loop Explained with a Practical Example

In this video, I explain the for loop step by step and show how it works using a practical example. You’ll learn what a for loop is, how its three parts (initialization, condition, and post-iteration) control execution, and how each iteration is performed. I also compare the for loop with the while loop and explain why the for loop is often considered a more convenient way to express repetition. To make things concrete, we build a small program that calculates compound interest over multiple years using a for loop. This example demonstrates how values change on each iteration and how loops are used in real programs. We also cover: for loop execution order infinite loops and conditions breaking out of a loop with break skipping iterations with continue Although the examples are shown in JavaScript, this for loop tutorial is language-agnostic, so the concepts apply to most programming languages. If you’re learning programming basics or looking for a clear for loop for beginners explanation, this video will help you build a strong foundation.
