What to expect
- Outputs a ready-to-use `export default { ... }` module.
- Object keys are unquoted where they're valid identifiers.
- Strings are safely quoted and escaped for you.

YAML to JavaScript Object Converter FAQ
Can I use this output in Node.js and the browser?
Yes, the generated ES module export works in any modern JavaScript environment.
Does it support CommonJS instead of ESM?
The default output uses `export default`; replace that with `module.exports =` if you need CommonJS.
Will special characters in strings break the output?
No, string values are serialized safely so quotes and special characters are escaped automatically.
Is there a difference between .yml and .yaml?
No. ".yml" and ".yaml" are just two file extensions for the exact same format — this converter accepts either one, so a "yml to JavaScript" conversion and a "yaml to JavaScript" conversion produce identical results.
