This code snippet failed on a test of 0, can anyone tell me why and how to fix it

Question

const dayOfWeek = moment().tz(timezone).format('d');

//test for weekend // 0 = sunday, 6=saturday

if ((dayOfWeek === 0 ) || (dayOfWeek == 6)
    {
        response = "closed";
    }
        else
    {
        response = "open";
    }

this part {dayOfWeek === 0) failed to test TRUE, really not sure why

Thank you for your help.

Did == 0 work? Need to understand the difference between == and === — zipzit, Oct 12 '21 at 14:44
check typeof dayOfWeek. if it's not number, then that's why it fails. — J_K, Oct 12 '21 at 14:48
`moment().format()` returns a string. You have `dayOfWeek === "0"`, not `dayOfWeek === 0`. — Jeremy Thille, Oct 12 '21 at 14:49

Double check if dayOfWeek is 0 (number) or '0' (string). I see that for the next check you use == and not ===. Have a look at strict equality
