### @parent blocks/language
Repeat code a fixed number of times.
Run part of the program the number of times you say.
### Example: Count to 4
This program will show the numbers 0, 1, 2, 3, and 4 one after another on the LED screen.
```blocks
for(let i = 0; i < 5; ++i) {
}
```
The Block Editor *for* loop is different than the Touch Develop *for* loop in an important way. The above for loop will iterate *five* times, with the loop variable *i* taking on values 0, 1, 2, 3, and 4. The Touch Develop for loop shown below will iterate four times:
```
for (let k = 0; k < 4; k++) {
basic.showNumber(i)
}
```
