- hosh 6y agoI stand corrected.
- jiofih 6y agoNo it is not. It is a primitive, this difference is well defined in the ECMAScript spec. Same for strings. An instanceof String is strictly not the same as a string primitive (and there are runtime consequences).
- ulucs 6y agoYou need to enclose numbers to access the prototype: 1.toString is undefined, whereas (1).toString() is "1"
