We use the [Airbnb JavaScript Style Guide](https://github.com/airbnb/javascript)
for JavaScript/TypeScript code with a little exception - we prefer 4 spaces
for indentation of nested blocks and statements.

For Python, we use [Black](https://github.com/psf/black) and
[isort](https://pycqa.github.io/isort/) to enforce the coding style and autoformat files.
You can use `dev/format_python_code.sh` to apply these formatters.
