About
JavaScript runtime built on V8. The default for backend JS — LTS releases, npm ecosystem.
What it does
Node.js runs JavaScript programs from files, standard input, inline scripts, or an interactive prompt. It includes built-in interfaces for files, operating system information, and name resolution. Programs can use CommonJS or ECMAScript modules.
Why it's ranked here
The case is strong for teams that need a cross-platform JavaScript runtime with predictable maintenance options. Stable APIs, signed releases, semantic versioning, extensive command-line controls, and documented module interoperability make it practical for long-lived systems.
What's good
File operations support synchronous, callback, and promise styles, so developers can choose clarity or performance deliberately. ECMAScript modules interoperate with CommonJS. Current and long-term-support release lines separate early access from stability, while signed checksums support binary verification.
Tradeoffs
Synchronous file work blocks the event loop and all further JavaScript execution. Promise-based file operations are neither synchronized nor thread-safe, so concurrent writes can corrupt data. Current releases permit breaking changes, and some command-line permission controls remain under active or early development.
How to use it well
Choose Node.js for teams writing command-line tools or system-facing applications in JavaScript. Prefer a long-term-support line for stability, asynchronous file operations for normal workloads, and explicit module markers. It supplies a runtime and built-in APIs, but not application architecture or deployment management.
Technical notes+
README.md defines Current, LTS, and Nightly release channels, semantic versioning, signed releases, and binary verification through SHASUMS256.txt.asc. Makefile supports make and ninja builds, Release and Debug modes, installation under PREFIX, C++ and JavaScript tests, addon tests, documentation checks, and coverage reporting. doc/api/cli.md documents script execution, stdin, the REPL, debugging, V8 options, and permission flags. doc/api/fs.md exposes synchronous, callback, and promise interfaces; its promise implementation uses the Node.js thread pool. doc/api/esm.md describes CommonJS interoperability, URL-based resolution, explicit module markers, and mandatory extensions for relative imports. doc/api/os.md and doc/api/dns.md expose operating-system and name-resolution APIs. pyproject.toml configures Ruff for Python tooling.
