ESLint plugin for ES5 users.

Sometimes someone doesn't want or can't to use Babel. Even if you support modern browsers or node.js, JS engines have bugs like broken block-scoping. Maybe you only want to forbid usage of for-of in your project.

If this concerns you, this plugin should help you.

npm install --save-dev eslint-plugin-es5

Add the plugin to your .eslintrc:

{
  "plugins": [
    "es5"
  ]
}

And then any of the rules listed below like this:

{
  "rules": {
    "es5/no-arrow-functions": "error"
  }
}

Also you can extend one of presets:

{
  "extends": [
    "eslint:recommended",
    "plugin:es5/no-es2015"
  ]
}
