While loops

A while statement repeats a block of instructions as long as a given condition is true.

A while loop generally has three components - the initialization, the condition, and the increment.

let i = 1
while (i < 10) {
    console.log(i)
    i = i + 1
}

It is important that the condition eventually becomes false, or the program will endlessly repeat the instructions and not do any further work.
