eslint-plugin-prefer-arrow-in-array

An ESLint plugin+rule to suggest arrow functions over function expressions as array elements.

Made for a project that's still using async.waterfall. (Don't do this. Use async/await instead.)

Quick hacky fork of prefer-arrow-callback from the ESLint core rules.
