What is while loop example?

A “While” Loop is used to repeat a specific block of code an unknown number of times, until a condition is met. For example, if we want to ask a user for a number between 1 and 10, we don’t know how many times the user may enter a larger number, so we keep asking “while the number is not between 1 and 10”.

What do you mean by while loop?

A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. The while loop can be thought of as a repeating if statement.

How does a while loop start?

First, we set a variable before the loop starts (var i = 0;) Then, we define the condition for the loop to run. As long as the variable is less than the length of the array (which is 4), the loop will continue. Each time the loop executes, the variable is incremented by one (i++)
