/**
* The `timer` module exposes a global API for scheduling functions to

*
* The timer functions within Node.js implement a similar API as the timers API
* provided by Web Browsers but use a different internal implementation that is
* built around the Node.js [Event Loop](https://nodejs.org/en/docs/guides/event-loop-timers-and-nexttick/#setimmediate-vs-settimeout).
