Does the ES6 specification include .finally()?

Many Promise libraries such as Q or Bluebird have a method called .finally that is executed on both success and error.

Does the ES6 promise also include this method? I haven't been able to find it. It doesn't seem to be present in Babel (6to5).

Any assistance in clarifying this would be greatly appreciated!

Thank you

Answer №1

As of now, ES6 has not been officially approved. It is still in the developmental phase. The latest draft does not include a finally function.
