![](/static/mb/events-0.png)

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++) {
}
```
