When the finally
method is called with argument onFinally, the following steps are taken:
"then"
, « thenFinally, catchFinally »).
A ThenFinally function is an anonymous built-in function that has a [[Constructor]] and an [[OnFinally]] internal slot. The value of the [[Constructor]] internal slot is a Promise
-like constructor function object, and the value of the [[OnFinally]] internal slot is a function object.
When a ThenFinally function F is called with argument value, the following steps are taken:
"then"
, « valueThunk »).
A CatchFinally function is an anonymous built-in function that has a [[Constructor]] and an [[OnFinally]] internal slot. The value of the [[Constructor]] internal slot is a Promise
-like constructor function object, and the value of the [[OnFinally]] internal slot is a function object.
When a CatchFinally function F is called with argument reason, the following steps are taken:
"then"
, « thrower »).
The resolve
function returns either a new promise resolved with the passed argument, or the argument itself if the argument is a promise produced by this constructor.
The resolve
function expects its
Promise
constructor.
The abstract operation PromiseResolve, given a constructor and a value, returns a new promise resolved with that value.
