## What it is
JSLint is Douglas Crockford's JavaScript code quality and coverage tool, distributed as a single zero-dependency, zero-config .mjs file. It can lint JavaScript in Node.js, browsers, and via a web demo.

## Use cases
- lint javascript code for quality issues
- generate code coverage reports for javascript
- check javascript style without configuration
- run a linter with zero dependencies
- lint javascript in the browser

## When to choose
- you want Crockford's strict, opinionated JavaScript style checking with no config
- you need a single-file linter with zero dependencies
- you want built-in code coverage alongside linting

## When to avoid
- you want configurable lint rules or plugin ecosystem (use ESLint)
- you need linting for TypeScript or JSX
- you prefer a flexible, team-customizable style guide

## Facets
- artifact type: library
- maturity: active
- function: linter, code-review, developer-tools
- domain: developer-tools, web-development
- platform: browser, cross-platform
- tags: javascript, code-quality, zero-dependency, zero-config, coverage, static-analysis, nodejs
