Asynchronous Utility Library

Overview

Concurrency

• mapPromises: Executes an array of promise-returning functions concurrently while limiting the concurrency to a specified number.

• promiseConcurrency: Executes an array of promise-returning functions concurrently with concurrency control.

Deferred

Provides a controllable promise whose resolution can be externally managed, facilitating resolution, rejection, and cancellation.

Event Loop

Facilitates asynchronous job execution in subsequent iterations of the event loop.

• schedule: Schedules a function to be invoked in the next iteration of the event loop.
• immediate: Schedules a function to be invoked immediately following the current event loop iteration.

Events

• EventEmitter: A simple event emitter implementation.
• BaseEvent: A base class for creating custom events.

Iterable

• forEachArray: An asynchronous alternative to Array.prototype.forEach.

• forEachArraySafe: An asynchronous alternative to Array.prototype.forEach that handles errors gracefully.

• forEachObject: An asynchronous alternative to Object.entries.

• forEachObjectSafe: An asynchronous alternative to Object.entries that gracefully handles errors.
