Clear local storage after 2 minutes

Question

I'm trying to clear some of the local storage items after 2 minutes using this code

I'm saving current time in the variable like :

   let time_now  = (new Date()).getTime();
   localStorage.setItem('otp_save_time', time_now);
   localStorage.setItem('set_otp', value);

Now i'm checking the current time with the saved time and clearing the item if time is greater than 2 minutes, but it is not clearing the item.

    let time_now  = (new Date()).getTime();
    if((time_now - saved_time) > 2 * 60 * 1000) {
       localStorage.removeItem('set_otp');
       localStorage.removeItem('otp_save_time');
    }

Does `setInterval` fulfill the requirement? Or you want to run it once? Then try to clear the setInterval execution later on. — Afzaal Ahmad Zeeshan, Nov 21 '20 at 05:40
Does this answer your question? [How can I make a function execute after 2 minutes and then at 2 minute intervals after that?](https://stackoverflow.com/questions/19533293/how-can-i-make-a-function-execute-after-2-minutes-and-then-at-2-minute-intervals) — Afzaal Ahmad Zeeshan, Nov 21 '20 at 05:41
How do you set `saved_time`? What if the user reloads the page so that variables are reset? — Barmar, Nov 21 '20 at 05:42
@Barmar: If user reloads the page then i will clear all the variables — user3653474, Nov 21 '20 at 05:44
