I’ve got the simple code below:

this.tenprintRequestPollTimeoutId =setTimeout(function () {
    console.log('Test 3: Timeout')
}, 1000);

But when I console.log(this.tenprintRequest), it returns an Object when I was expecting a number. Any help with be greatly appreciated.
return object is:

Object {
  "hasRef": [Function hasRef],
  "ref": [Function ref],
  "refed": true,
  "refresh": [Function refresh],
  "unref": [Function unref],
  Symbol(Symbol.toPrimitive): [Function [Symbol.toPrimitive]],
}
