js reverse while loop

Question

i'm trying to make do...while loop with reversed order and with "random step".

var estam = 100;
do
{

   //   some things, that can change variable "rd"

   estam -= Math.floor((Math.random()*rd)+1)
}
while (estam < 1);

But browsers just perform do once.

I'm trying to get: "do something with some things and decrease variable estam accordingly to those things (and those some operations) as long as estam is bigger than zero".

Or i need to make ordinary loop with steps, and in each step check estam than jump out to function and back ?

If you want it to loop while estam is bigger than zero, you should specify that in the while condition as estam > 0. What you have now is not equivalent to what you say you want. — Martin Dinov

I thought that last line while (estam < 1); is the conditional limit to break te loop. My mistake. — Bri.H.

The do while expression should be read as "do this work while this expression is true".

You are looking for

while (estam > 0);

which will ensure the loop breaks once estam is less than 0, when the expression is no longer true.

So simple, I thought that last line while (estam < 1); is the conditional limit to break te loop.
