@parent blocks/language

Repeat code a fixed number of times.

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++) {
}
