chirag64 / Sleep.js
Last active December 23, 2015 00:09
Use this only in terms of desperation because this function will keep the CPU busy as long as it exits. I hate JavaScript for the lack of a proper sleep function.
function sleep(milliseconds) {
var start = new Date().getTime();
while(true) {
if ((new Date().getTime() - start) > milliseconds) {
break;
}
}
}
