## What it is
linq.js is a pure JavaScript implementation of the .NET LINQ library with no dependencies, providing all original .NET methods plus additions. It supports ES modules, CommonJS, TypeScript type definitions, and Deno.

## Use cases
- query and transform arrays with LINQ-style chained methods in JavaScript
- port C# LINQ code to JavaScript
- filter, map, and aggregate collections using where/select/aggregate
- use lazy evaluation over sequences in Node.js or Deno
- work with typed collections in TypeScript projects

## When to choose
- you want .NET LINQ semantics in JavaScript with zero dependencies
- you're migrating or sharing logic between C# and JavaScript codebases
- you need a stable, well-typed collection query library for Node, Deno, or the browser

## When to avoid
- you prefer native JS array methods or a more idiomatic functional library like lodash
- you need async/streaming pipelines rather than synchronous enumerable sequences
- your project requires CommonJS and you need the latest version

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: developer-tools, programming-languages
- platform: browser, cross-platform
- tags: linq, javascript, enumerable, collections, functional-programming, typescript-definitions, algorithms, nodejs, deno
