What Is a Loop in Coding? Definition and Examples for Kids

A loop is a coding instruction that tells a computer to repeat the same set of steps automatically — over and over — until a condition is met. Instead of writing the same command many times, a programmer writes it once inside a loop, and the computer runs it as many times as needed.

Types of Loops

Most programming languages use two main kinds of loops. A for loop repeats an action a fixed number of times — for example, "jump 10 times." A while loop keeps repeating as long as a condition stays true — for example, "keep walking while the path is clear."

In Scratch, the block-based language many Malaysian kids learn first, a "repeat 4" block wrapped around a "move" and "turn" command draws a perfect square: the cat sprite moves and turns four times without you copying the blocks four times. A single loop can replace hundreds of lines of code — printing the numbers 1 to 100 would take 100 separate commands, but a loop does it in just two or three lines.

Why It Matters for Kids

Loops are one of the first "big ideas" in computational thinking, a skill highlighted in Malaysia's KSSR curriculum and STEM education. Learning loops teaches children to spot patterns and think efficiently instead of repeating work by hand. Kids explore loops hands-on in Algonova coding classes, starting with Scratch before moving to text languages like Python. To see how loops fit the bigger picture, read what is coding for kids.

Loops in Coding Explained Simply

In coding, a loop lets a computer repeat the same steps automatically instead of writing them out many times. Loops save effort and reduce mistakes, because you fix the steps in one place rather than in dozens of copies. Whether a child draws a square in Scratch or counts to 100 in Python, the same loop idea does the repeating for them.
