How can I make code execute after x amount of time without using setTimeout()

Question

Here's my situation, my goal is to have a function execute after x amount of time, now setTimeout() works cool for that except it unreliable in my use case, I've also considered using Date.now() and doing a check every second to see if x amount of time has passed but that's very unrealistic in my use case also, I'm willing to try any suggestions!

I'd like to add that my use case is setting a reminder from a function that I would have made, I've got access to a key-value database and this solution needs to work even if my process is killed then reopened.

Answer 1

you can make a delay function and await it before execution of the next line

function Delay(seconds){
    return new Promise(resolve => {
         setTimeout(() => {
             resolve(true)
         }, seconds * 1000) // convert seconds to ms
    })
}

now you can use it like this

//some code here
await Delay(5) // wait 5 seconds
// other codes here

It may be helpful for you

function setTime(milisec){
        var startTime =new Date().getTime();
        for(var i=0; i<milisec; i++){
            if((new Date().getTime()-startTime) > milisec)
                break;
         }
         console.log('Hii I am executed');
    }
    setTime(10000000);
