STEP 1

Several steps.

for repeats the code. At first, step is 1 and then grows 1 to the border.

for (let step = 1; step <= 3; step++) {
  console.log(step);
}

✦ There will be 1, 2, 3.

STEP 2

Знак <= разрешает взять число на границе. Если поставить <, последнее число не попадёт в цикл.

for (let step = 1; step < 3; step++) {
  console.log(step);
}

✦ Only 1 and 2 will appear here.
