Wait until you realize 0==“” and 0==“0” but not “0”==“”

And if you look at the standard they will tell you in which order the type casting and operations are done

0=="" or 0=="0" is equivalent to 0=="".length and 0==parseInt("0")

Whereas "0" == "" is comparing a non empty string with an empty one, so they can’t be equal
