10.3 while

The while statement loops on a code block as long as a condition is true.

The following code loops until n reaches the value 10:

let mut n = 1;
while n < 10 {
  print!("{n}, ");
  n += 1;
}

As for the loop statement:

• The continue keyword is used to skip a step.

• The break keyword is used to exit the loop prematurely.

• Labels are used to exit nested loops.
