typescript - Execute a promise until a condition is met (within a while loop) -

i want encapsulate promise within while loop, method executed until condition met. i've tried implement this, end infinite promises generated until stack overflow occurs.

i want implement following in typescript:

while (responsesuccess === false) {     myclass.executescript.then((thiswassuccessful: boolean) => {          responsesuccess = thiswassuccessful;     }); 

i know little unconventional, script have created request server application executes. not return success first time, or n times (not can change).

try use await operator.

while (responsesuccess === false) {   responsesuccess = await myclass.executescript; }); 

ps: should use ts 2.1 or higher target es5
