The while Loop

Repeat while true

A while loop runs as long as its condition is true:

let count = 0

while (count < 5) {
  console.log(count)
  count++
}
// Prints: 0, 1, 2, 3, 4

The condition is checked before each iteration. If it starts false, the loop body never runs. Always ensure something inside the loop eventually makes the condition false.
