The Classic for Loop

Count and repeat with an index.

Why Loops Exist

When you need to repeat work many times, copying code is painful. A loop runs the same block again and again so you write it just once. 🔁

The classic for loop repeats a block a known number of times, using a counter you control from start to finish.

for (var i = 0; i < 3; i++) {
  print('Hello');
}
