Why can't a variable be set to a .toString(), but you can can call toString() on a return value?

Question

function s(e) {
    return e.toString();
}

var a = s(3); // works

var b = 3.toString(); // error

For example, set var a to the return value of s() that returns the first argument.toString(), but you can't set var b to 3.toString()

Javascript is expecting number(s) after the decimal, you can still do this, but you need to put your number in parenthesis:

(3).toString() = "3"

Or `3..toString()` (not that this isn't even more confusing :P ) – Felix Kling Jun 05 '16 at 02:11
