Educational examples are not a substitute for a real compiler or version-specific documentation. JavaScript, Python and SQLite demos run in isolated browser contexts when supported; Python and SQL load an online WebAssembly runtime on first use. Other languages receive structural hints, not compiler validation. No visitor code executes on WordPress.
