A while loop checks the condition (well, the expression) behind the while before each iteration and stops executing the loop body when the condition is False . So while False means that the loop body will never execute.

Whats the difference between a loop and a while loop?

For loop vs While loop The difference between for loop and while loop is that in for loop the number of iterations to be done is already known and is used to obtain a certain result whereas in while loop the command runs until a certain condition is reached and the statement is proved to be false.

What is difference between while loop and do while loop and for loop?

What is the difference between for loop and while loop in Javascript?

while — loops through a block of code once; then the condition is evaluated. If the condition is true, the statement is repeated as long as the specified condition is true. for — loops through a block of code until the counter reaches a specified number.
