Loops

Loops let you repeat code multiple times. Instead of writing the same code over and over, you can tell JavaScript to run it as many times as you need.

What You'll Learn

for loops - Run code a specific number of times
while loops - Run code while a condition is true
for...of loops - Iterate through arrays elegantly

Why This Matters

Loops are essential when working with collections of data:

Process every item in a shopping cart
Validate each field in a form
Display a list of search results
Repeat an action until a goal is reached

Combined with arrays and the iteration methods you learned earlier, loops give you complete control over repetitive tasks.

Let's learn to make JavaScript do the repetitive work for us!
