How to use Timers in React Native

A timer is a handy tool that can be used within any component inside your application and is particularly useful in displaying temporary screens or animated content.Although they are commonly used, the implementation can sometimes be tricky, most frequently when you have a lot of things going on in the background.

The easiest way to set a timer is to use the well known setTimeout() method which calls a function or evaluates an expression after a specified number of time (milliseconds). From the example below, once the myFunction() is called, an alert displaying “hello” will be displayed after 3 seconds.

Now for a real life example of how to use timers in react native, I’ll show you how they were implemented using an animated splash screen that displays whilst the user is being authenticated.
