Issue

There's one small discrepancy between our defined eslint rules and our (default, it seems) prettier config. eslint wants arrow function arguments always wrapped in parentheses, whereas prettier omits them for single-argument arrow functions.

What this means is if you autoformat your source code with prettier, sometimes it will fail eslint due to this discrepancy.

Solution

Add prettier config to package.json to always wrap arrow function arguments in parens.

None

Testing

Mostly N/A as this is a tooling issue, but if we start seeing lint errors after running prettier, let me know.
