 * :wrench: [`unicorn/catch-error-name`](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/master/docs/rules/catch-error-name.md) – *changed* – I prefer `err` over `error` as I find `error`to be a far too similar name to the built in `Error` class
 * :mute: [`unicorn/explicit-length-check`](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/master/docs/rules/explicit-length-check.md) – *deactivated* – I don't see an issue with `if (string.length)` instead of `if (string.length !== 0)`
 * :warning: [`unicorn/unicorn/no-await-expression-member`](https://github.com/sindresorhus/eslint-plugin-unicorn/blob/master/docs/rules/unicorn/no-await-expression-member.md) – *changed* – eg. useful in chai tests
