## Getting started

Create a `test.js` and run the example `just example prettier` from
`crates/oxc_prettier/examples/prettier.rs`, follow the code structure
and read the references documented at the top of the files.

# Tasks

- [ ] Implement a test runner in Rust which extracts the snapshots and
do a comparison over it
- [ ] Establish a way to pass all the tests by manually porting code
- [ ] Pass as many tests as possible in
