Timers are polyglot. They are very useful in many use cases. Almost all major programming languages supports them, and Node.js is no exception. It's actually more simple in Node because Node lets us reuse our existing learning of timers.
In this post, I will describe and demonstrate what timers are, how to use them, what the syntax looks like, and then how you can leverage them in your applications. One common example, if you want to retrieve data from a REST API on specific interval, you can achieve very easily using timers. So, even if you are new to JavaScript or timers, this post will help you understand these concepts. If you are interested in knowing more about Node, you can also check my other articles as well.
