Loop different functions with different timing

I have some functions, for example, afoo(), bfoo() and cfoo(), I want that functions run simultaneously/paralel in a loop with different timing.

Example:

afoo() --> run one time every 5 minutes

bfoo() --> run one time every 10 minutes

cfoo() --> run one time every hour

Is there anyway to do that? Maybe with SetInterval()?

You could use setInterval method to call a function on every fixed time delay, in the most case it's used in conjunction with clearInterval method to stop the repeated calls, here is an example:

var interval = setInterval( function () {
    afoo( function (err) {
        // clear interval if an error occured
        if ( err ) {
            console.log(err);
            clearInterval(interval);
        }
    });
}, 5 * 60 * 1000);

If you want more control then use node-cron module, it has the same cron pattern used by linux systems, Example:

const CronJob = require('cron').CronJob;

// run afoo function every 15 min
var job = new CronJob('00 15 * * * *', afoo);
