Sorry, but the semantics of "this" in JavaScript are crazy — and I think that's being generous. There are a few common use cases that trip people up, e.g., situations where "this" becomes bound to another object like the global window object, and I'd expect an experienced JavaScript programmer to know those. It depends on what you mean by "down cold," obviously, but if your standard is "either they have the semantics of the 'this' keyword down cold or they're incompetent" then virtually all JavaScript programmers I know (including myself) are incompetent. |
