Normalize layout with Prettier after a strict standard-ECMAScript parse.
Submit the example or replace it with your own input. Source is parsed but never executed.
Explicit static behavior
Formatting changes presentation rather than program intent. Quote style and semicolon preference are explicit inputs while line width and indentation use stable documented defaults.

The formatter first rejects unsupported or invalid syntax, then uses the pinned Babel and ESTree plugins. It does not execute formatted output.
Tool Swim parses source as standard ECMAScript inside a disposable Web Worker with a 2,000 ms deadline. It never calls eval, Function, imported modules, or user code.
Source and results stay in the current browser tab. The public tool makes no API request, stores no preset, and does not require an account or telemetry.
