Uncaught SyntaxError: Unexpected token instanceof (with Chrome Javascript console)

Question

I am surprised that the following code when input into the Chrome js console:

{} instanceof Object

results in this error message:

Answer 1

{}, in that context, is a block, not an object literal.

You need change the context (e.g. by wrapping it in ( and )) to make it an object literal.

({}) instanceof Object;
