Sync delay like Arduino delay function built-in

Hi guys,

I need your help because I need execute a sync delay similar to Arduino function built-in. Like this:

module.moveServo(0,1000);
module.wait(5000); // this code must be stop the execution until the time is completed
module.moveServo(1,1000);

I tried with:

Contents of module_file.js:

exports.wait = (time) =>{
  var i = 0;
  while(i < time * 10) {  i++; }
  console.log("Done!");
}

I tried also with:

const startPoint = new Date().getTime()
  while (new Date().getTime() - startPoint <= ms) {/* wait */}

And the result when tried to call more that 3000 ms is a dump and reset with this log:

What's happened? I'm very stressed with this.
