So, a while loop is useful when you don’t know how many times you want a block of code to execute beforehand.

Detailed explanation-2: -The repeat / until loop is a loop that executes a block of statements repeatedly, until a given condition evaluates to true . The condition will be re-evaluated at the end of each iteration of the loop, allowing code inside the loop to affect the condition in order to terminate it.
