JavaScript code gets the Elide global, Node built-in modules, elide: database modules,
and Web globals. Suite results are in the Compatibility Matrix. Java and Kotlin programs: see
JVM APIs.
Built-in modules
Node modules resolve with or without the node: prefix. Each page links the upstream documentation, lists
differences, and ends with a generated reference: exports, anything not implemented, and suite results.
