How to run this function on an interval?

Question

I am trying to run everything within the checkUser() function but its not running on the interval specified. Maybe there is a better way to do this? I am just trying to check the address every few minutes. The line const accounts = await ethereum.request({ method: 'eth_accounts' }); does get the address and works fine if I just run it once. Just need to try do it on an interval though. Full code below:

function checkUser()
            {
                window.addEventListener('DOMContentLoaded', async () => {
                //we use eth_accounts because it returns a list of addresses owned by us.
                const accounts = await ethereum.request({ method: 'eth_accounts' });
                //We take the first address in the array of addresses and display it
                // getAccountsResult.innerHTML = accounts[0] || 'not able to get accounts';

                 console.log(accounts); //test one

                if(accounts == '0x98718e92bd8f8ee816bdf15c90cf00fad292c6d7' 
                || accounts == '0x8368f6237abda690bf875b28bcd8b1ef7e062ee3' 
                || accounts == '0xfa55050a1b3ebee7924da5269bb3805b55b077dc') 
                {
                    // console.log("you are going in!");
                    // window.location.href = "members_home.html";
                }
                else
                {
                    console.log(accounts); //test one
                    window.location.href = "normal_home.html";
                }
             });

            }
            setInterval(checkUser, 50);

Why are DOMContentLoaded and setInterval inside your checkUser function ?

Your instructions order is all wrong.

Reading your code, I think you don't even want to use setInterval...

I guess what you want to do is :

1. wait for DOMContentLoaded to define checkUser

2. checkUser to do the ethereum.request

   window.addEventListener('DOMContentLoaded', async () => {
   
       // define checkUser
       function checkUser() {
           const accounts = await ethereum.request({ method: 'eth_accounts' });
           //We take the first address in the array of addresses and display it
           // getAccountsResult.innerHTML = accounts[0] || 'not able to get accounts';
   
           console.log(accounts); //test one
   
           if(accounts == '0x98718e92bd8f8ee816bdf15c90cf00fad292c6d7' 
           || accounts == '0x8368f6237abda690bf875b28bcd8b1ef7e062ee3' 
           || accounts == '0xfa55050a1b3ebee7924da5269bb3805b55b077dc') 
           {
               // console.log("you are going in!");
               // window.location.href = "members_home.html";
           }
           else
           {
               console.log(accounts); //test one
               window.location.href = "normal_home.html";
           }
       }
   
       // run checkUser
       checkUser();
   }
