eslint-plugin-foo-bar

This rule is created for educational purposes to explain how to create an ESLint custom rule and plugin.

ESLint plugin that only allows you to assign "bar" to const foo.

For example, the rule would give an error for the following:

const foo = "baz"; // Bad :(

The rule accepts the following:

const foo = "bar"; // Good :)
