How do you create a loop in JavaScript?
Statement 1 sets a variable before the loop starts (var i = 0). Statement 2 defines the condition for the loop to run (i must be less than 5). Statement 3 increases a value (i++) each time the code block in the loop has been executed. Normally you will use statement 1 to initialize the variable used in the loop (i = 0).
