Description

This RFC proposes refactoring the mapFunAsync function in @stdlib/utils-async-map-function to return an object that allows querying the status of in-flight asynchronous operations. This aligns with the goal of achieving feature parity with async.js while improving observability of async execution states.

Related Issues

Related issues #9 which states that we need to achive parity with async.js.
Changes:

Modified mapFunAsync to return an object containing:

status: Tracks the state (pending, completed, or error).

getStatus(): Method to retrieve the current state.

cancel(): Method to cancel execution (if applicable in the future).

Updated tests to validate the new behavior.

Updated documentation to reflect the API changes.

Motivation:
This refactor improves the usability of mapFunAsync by enabling users to track ongoing async operations, which is particularly useful in long-running tasks or when debugging async workflows.
