info: |
IsConstructor ( argument )
The abstract operation IsConstructor takes argument argument (an ECMAScript language value).
It determines if argument is a function object with a [[Construct]] internal method.
It performs the following steps when called:
If Type(argument) is not Object, return false.
If argument has a [[Construct]] internal method, return true.
Return false.
