How to run while loop for N seconds in TypeScript

Answer 1

function sleep(seconds: number) {
    seconds = (+new Date) + seconds * 1000;
    while ((+new Date) < seconds);
}

let startTime = Date.now(); // Get the current time
const duration = 3000; // Duration in milliseconds (e.g., 3000ms = 3 seconds)
const endtime = startTime + duration;
  
while (startTime < endtime) {
    sleep(1); // Sleep for 1 second
    startTime = Date.now();
    console.log(new Date(startTime).toString());
}
