Block Editor

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++) {
}
