Repeat Until Loop in JavaScript?

Question by Guest | Last update on 2021-06-13 | Created on 2013-03-06

I need a Repeat-Until loop in JavaScript, as it is possible, for example, in Delphi. So, I want to repeat something until a certain condition is met.

Is there such a loop in JavaScript? I've played around with different "Repeat" and "Until" combinations, but it is just not working.

The Repeat-Until-Loop in JavaScript is constructed with "do" and "while", for example like this:

var k = 0;

do { 
   k = k + 1;
} while (k < 10);

The variable "k" will be increased as long as "k" is smaller than 10.

So, contrary to Delphi, the condition is reversed: The loop is not executed until the condition is met, but until the condition is no longer met.
