I will assume your java tag should be javascript since it looks like you're talking about nodejs.

It's a bit hard to tell exactly what you're trying to do, but you can launch new processes from within nodejs using the child process module with either .exec() or .spawn().

So, if you have one nodejs process running already, you can use setTimeout() and the child process module to launch another process at some future scheduled time.

For example, here's an example from the child_process doc pages wrapped inside a setTimeout():

const exec = require('child_process').exec;

setTimeout(function() {
    const child = exec('cat *.js bad_file | wc -l', (error, stdout, stderr) => {
        console.log(`stdout: ${stdout}`);
        console.log(`stderr: ${stderr}`);
        if (error !== null) {
          console.log(`exec error: ${error}`);
        }
    });        

}, 10 * 1000);
