Only arrow functions in ESLint?

Anser based on @JohannesEwald comment and @KevinAmiranoff answer.

I’m using the following rules:

https://www.npmjs.com/package/eslint-plugin-prefer-arrow

https://eslint.org/docs/rules/prefer-arrow-callback

https://eslint.org/docs/rules/func-style

npm install -D eslint-plugin-prefer-arrow

.eslintrc or package.json with eslintConfig:

"plugins": [
  "prefer-arrow"
],
"rules": {
  "prefer-arrow/prefer-arrow-functions": [
    "error",
    {
      "disallowPrototype": true,
      "singleReturnOnly": false,
      "classPropertiesAllowed": false
    }
  ],
  "prefer-arrow-callback": [
    "error",
    { "allowNamedFunctions": true }
  ],
  "func-style": [
    "error",
    "expression",
    { "allowArrowFunctions": true }
  ]
}

I think this works really well. If you need to disable the rules for a specific line I do it like this:

// eslint-disable-next-line func-style, prefer-arrow/prefer-arrow-functions
