Necessary Utilities

Necessary is a JavaScript utility library offering a curated collection of functions inspired by larger libraries like Lodash and Async. It aims to provide essential utilities with a relatively small footprint and transparent implementations, particularly for asynchronous operations, to aid debugging. The library, currently at version 17.1.8, features a clear separation of concerns, with distinct utility collections for browser-only environments (e.g., Ajax), Node.js-only environments (e.g., File System, Shell), and universal utilities usable in both (e.g., Array, String, Asynchronous). It exports utility collections as plain JavaScript objects, from which individual functions can be destructured. The project appears actively maintained with regular updates, although a specific release cadence isn't explicitly stated. Key differentiators include its modular structure, explicit environment targeting, and a focus on simplicity over feature breadth.
