setTimeout in React Native

Question

Answer 1

On ReactNative .53, the following works for me:

 this.timeoutCheck = setTimeout(() => {
   this.setTimePassed();

'setTimeout' is the ReactNative library function.
'this.timeoutCheck' is my variable to hold the time out object.
'this.setTimePassed' is my function to invoke at the time out.
