The for Loop

Counting iterations

A for loop combines initialization, condition, and update in one line:

for (let i = 0; i < 5; i++) {
  console.log(i)
}
// Prints: 0, 1, 2, 3, 4

The $3$ parts are:

$1.$ let i = 0 - runs once at the start

$2.$ i < 5 - checked before each iteration

$3.$ i++ - runs after each iteration

This is the most common loop for counting.
