> var obj={}.valueOf.call(obj); // ToObject in case primitive value passed
Can you explain how this works?
- Why {} and not Object.prototype?
- I know valueOf as a method that returns a primitive if an object can be
converted to one and |this|, otherwise. Oddly enough, this works both in strict
mode and in non-strict mode, as explained in the comment.
Thanks!
