The "length" property of Array.prototype.concat
info: |
22.1.3.1 Array.prototype.concat ( ...arguments )
The length property of the concat method 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. Optional parameters (which are indicated with brackets:
[ ]) or rest parameters (which are 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 }.
includes: [propertyHelper.js]
