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.

19.5.6.2 Properties of the NativeError Constructors
Besides the length property (whose value is 1) [...].
17 ECMAScript Standard Built-in Objects:
Every built-in Function object, including constructors, has a length
property whose value is an integer. Unless otherwise specified, this
value is equal to the largest number of named arguments shown in the
subclause headings for the function description, including optional
parameters. However, rest parameters shown using the form “...name”
are not included in the default argument count.
Unless otherwise specified, the length property of a built-in Function
object has the attributes { [[Writable]]: false, [[Enumerable]]: false,
[[Configurable]]: true }.

17 ECMAScript Standard Built-in Objects:
Every built-in Function object, including constructors, that is not
identified as an anonymous function has a name property whose value
is a String.
Unless otherwise specified, the name property of a built-in Function
object, if it exists, has the attributes { [[Writable]]: false,
[[Enumerable]]: false, [[Configurable]]: true }.
