Features

• Asynchronous Collection Processing - Provides asynchronous mapping, filtering, and reducing operations for arrays and objects using non-blocking functions.
• Asynchronous Task Managers - Orchestrates the execution of asynchronous functions using callbacks or promises to manage flow and errors.
• Asynchronous Task Orchestrators - Acts as a comprehensive orchestrator for managing complex asynchronous task dependencies, queues, and concurrency limits.
• Asynchronous Collection Processing - Provides asynchronous filtering, iteration, and transformation utilities for arrays and objects.
• Asynchronous Collection Iteration - Applies asynchronous functions to each item in an array or object using parallel or series execution.
• Collection Processors - Offers a comprehensive set of tools for mapping, filtering, and reducing collections using parallel or series execution.
• Dependency Graph Runners - Executes tasks based on directed dependency graphs to resolve execution order and circular references.
• Sequential Task Dependencies - Executes functions in a series where each task consumes the output of the previous step as input.
• Sequential Task Execution - Executes a set of functions sequentially and stops immediately if any task returns an error.
• Async-Await Flow Control - Provides native integration for async functions by automatically handling returned promises and thrown errors.
• Asynchronous Control Flows - Provides core utilities to manage the execution order and error propagation of asynchronous tasks via callbacks.
• Asynchronous Flow Libraries - Provides a comprehensive suite of functional utilities for managing asynchronous execution and coordination in Node.js and the browser.
• Asynchronous Element Transformations - Produces a new array by running each item through an asynchronous iterator while preserving the original order.
• Promise-Callback Unification - Unifies callback-style and promise-based functions automatically to manage return values and rejections.
• Asynchronous Orchestration Patterns - Manages complex sequences of asynchronous tasks using parallel and series patterns to coordinate flow.
• Concurrent Task Limiters - Implements utilities that limit the number of active parallel operations to prevent system resource exhaustion.
• Asynchronous Task Queueing - Controls the flow of asynchronous tasks using concurrency limits and payload constraints.
• Task Retry Policies - Implements automatic retry strategies with configurable intervals and exponential backoff for failing tasks.
• Task Scheduling - Calculates execution order and manages timing for timeouts, retries, and deferred tasks.
• Parallel Task Spawning - Spawns multiple concurrent operations within a shared scope and merges all results upon completion.
• Promise-Callback Unification - Unifies native promises and traditional callbacks into a consistent execution interface.
• Asynchronous Collection Reduction - Combines an array into a single value by applying an asynchronous iterator in series.
• Asynchronous Collection Sorting - Orders a list based on the results of an asynchronous iterator applied to each element.
• Asynchronous Item Matching - Checks if some or all elements in a collection satisfy an asynchronous test and returns a boolean result.
• Asynchronous Item Search - Returns the first value in a collection that satisfies an asynchronous truth test.
• Asynchronous Result Flattening - Applies an asynchronous iterator to each item and concatenates the resulting arrays into a single list.
• Task Racing - Async runs multiple tasks simultaneously and returns the result from the first one that completes.
• Execution Timeouts - Limits the execution time of asynchronous functions by triggering failure when a specified duration expires.
• Until Loop Structures - Implements until-loop semantics to execute asynchronous functions repeatedly until a target state is reached.
• Dependency Graph Resolution - Calculates task execution order by analyzing a map of requirements to handle complex interdependencies.
• Event Loop Deferral - Provides utilities to schedule functions on a later event loop tick, moving long-running logic out of the current cycle.
• Function Composition - Combines multiple asynchronous functions into a new function where each stage consumes the return value of the next.
• Asynchronous Pipelines - Combines multiple asynchronous functions into a single pipeline where each stage consumes the output of the previous task.
• Retry Policies - Provides robust retry logic for failing asynchronous functions with configurable intervals and exponential backoff.
• Task Result Aggregation - Gathers results and errors into a single object to ensure task failures do not interrupt the main execution flow.
• Success-Based Parallel Sampling - Executes multiple tasks in parallel and returns success as soon as any single task completes successfully.
• Callback and Promise Unifiers - Implements a unification bridge allowing callback-style and promise-based functions to operate within the same execution interface.
• Asynchronous Control Flow - Asynchronous utility library for Node and browsers.
• Control Flow Utilities - Asynchronous utilities for Node and browser.
• Flow Control - Utilities for handling asynchronous tasks.
