firebase auth.currentUser.email error/bug?

clearly ([e-mail] === “[e-mail]” || “[e-mail]”) should return false

so why is it printing “email in first : [e-mail]”

when it should print “email was : [e-mail]”

code below

let email = auth.currentUser.email


if(email === "[e-mail]" || "[e-mail]") {
    alert("email in first : " + auth.currentUser.email )
    checkUserIsNotAlreadyInGame() 
    return
        } else {
            alert("email was :" + auth.currentUser.email )
            return
        }

prints “email in first : [e-mail]”

Answer

your expression will always evaluate to true because it falls to the “[e-mail]” string which always evaluates to true in the condition.

change your condition to the following:

if(email === "[e-mail]" || email === "[e-mail]")

then you’d get the expected result
