In this tutorial, we will learn about the interval and timer operator of RXJS.

Interval Operator

Interval Operator make calls on some interval

Example:

import { interval } from "rxjs";    
------------------------------
const source$= interval(2000);
 
    source$.subscribe((res) => {
      console.log(res);
    });

Output: 
1,2,3,4,5...........

The above example will print the response every two seconds as defined in the interval operator.

Timer Operator

Timer works same as but takes two argument delay, interval.

Syntax:

timer(delay,interval)

Example:

import { timer} from "rxjs";    

------------------------------

const source$ = timer(5000, 1000);

    source$.subscribe((res) => {

      console.log(res);

    });

Output: 

1,2,3,4,5...........

In Above eample timer will start after five seconds and will run for every seconds untill we stop.
