fastq

Fast, in-memory work queue for Node.js and browsers. Current stable version is 1.20.1, actively maintained. Provides a lightweight alternative to async.queue and neoAsync.queue, with benchmarks showing it's nearly as fast as setImmediate. Supports both callback and promise APIs, TypeScript typings, and features like pause/resume, drain events, and concurrency control. Ideal for task scheduling with minimal overhead.
