If I want to perform a task at least after 5 seconds then is it a good idea that I use recursion & setTimeOut() instead of setInterval()? I wrote below to achieve this:
let interval=5000;
function job(){
let startTime = new Date();
fetchData();//actual task to perform at least after 5 seconds, can take more less or more than 5 seconds
let elaspedTime = (new Date().getTime()) - startTime.getTime();
let waitTime = (interval * 1000) - elaspedTime;
if (waitTime > 0) {
setTimeout(() => {
job();
}, waitTime);
} else {
job();
}
}
You can use a set interval each 5 seconds. Remeber that setInterval returns and Id which you can use, to stop the interval once you got thet data.
function getData(host) {
// your code
clearInterval(host.id);
}
var host = {};
host.id = setInterval(getData.bind(null,host),5000);
I used this pattern to have acces in the function to the intervalId. You can read more about this in: Send interval id as an argument to executing function
You can create a promise wait function, and resolve the promise after 5 seconds.
const wait = (ms) => new Promise((resolve) => setTimeout(resolve, ms));
const fetchData = () => console.log("===> fetching data");
const job = async () => {
console.log("===> Job Started");
await wait(5000);
console.log("===> Time to Fetch the data");
fetchData();
};
job();
