A community-maintained set of compatibility tables tracking ECMAScript (ES5, ES6, ES Next, and non-standard) feature support across JavaScript engines, browsers, compilers, and Node.js versions. Data files are built into browsable HTML pages showing which platforms support which language features.

Use cases

• check which browsers support a specific ES6 feature
• compare JavaScript engine support for ES Next proposals
• find out if a transpiler like Babel supports a given feature
• look up Node.js support for a JavaScript language feature
• verify non-standard feature support across platforms

When to choose

• you need authoritative, community-audited data on ECMAScript feature support across runtimes and browsers
• you are deciding whether a language feature is safe to use in your target environments
• you want to check transpiler/compiler coverage of ES6 features

When to avoid

• you need runtime feature detection in production code (use a feature-detection library instead)
• you need compatibility data for CSS, HTML, or web APIs rather than the JavaScript language itself
• you need machine-readable API access without parsing the JS data files yourself
