Definition: The while statement specifies a block of code that is to be run multiple times. It will run while either the while condition is met or until a break statement within the do block is run. While can also be used to create a do/while statement that will test the condition at the end of the loop instead of at the beginning. While is a reserved word and cannot be used for anything other than declaring a while or do/while statement.
Examples:
while {...}
