asyncGroup

The asyncGroup() function aggregates synchronous or asynchronous Right values from an object, array, or tuple into a Success. It awaits entries in order and returns the first Left encountered.

Interactive example

The const generic parameter automatically infers an array literal as a tuple, without an as const assertion.

Syntax

await E.asyncGroup(group)

Parameters

• group: Object, array, or tuple containing Either, Promise, or Future values, or functions returning any of these types.

Return value

• A Promise of a Success containing an object, array, or tuple of unwrapped values when every entry produces a Right.
• Otherwise, a Promise of the first Left in declaration order. Functions placed after that Left are not called.
