ESLint plugin for ES5 users.

eslint-plugin-es5

ESLint plugin for ES5 users.

Why?

Sometimes someone doesn't want to or can't 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.

Installation

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

Usage

Add the plugin to your .eslintrc:

{
  "plugins": [
