4.7 While Loops
JavaScript also supports two additional types of loops: while and do .. while loops. These loops differ from for loops in that they test a condition evaluating to true or false at each iteration step, rather than iterating a range of numbers or elements in an object. We’ll cover the syntax of both while loop types and look at some considerations of their usage.
