description: Tests that Temporal.Duration.from meets the requirements for built-in objects
|
|
info: |
|
|
Built-in functions that are not constructors do not have a "prototype" property unless
|
|
otherwise specified in the description of a particular function.
|
|
|
|
Unless specified otherwise, a built-in object that is callable as a function is a built-in
|
|
function object with the characteristics described in 10.3. Unless specified otherwise, the
|
|
[[Extensible]] internal slot of a built-in object initially has the value true.
|
|
|
|
Unless otherwise specified every built-in function and every built-in constructor has the
|
|
Function prototype object [...] as the value of its [[Prototype]] internal slot.
