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.
