The While loop repeats the same code until it encounters a stop condition.

The while loop is a programming construct that repeats a block of code an undetermined number of times until a condition is met. Let's imagine we want to know how many times we can divide a certain integer by 2 before it becomes less than or equal to 1.

When you know how many times the loop should run, you should use a for loop. Use a while loop if you want the loop to break depending on something other than the number of times it runs.
