ESLint plugin which disallows each ECMAScript syntax.

## 🏁 Goal

[Espree](https://github.com/eslint/espree#readme), the default parser of [ESLint](https://eslint.org/), has supported `ecmaVersion` option.
However, the error messages of new syntax are not readable (e.g., "unexpected token" or something like).

When we use this plugin along with the latest `ecmaVersion` option value, it tells us the readable error message for the new syntax, such as "ES2020 BigInt is forbidden."
Plus, this plugin lets us disable each syntactic feature individually.

## 📖 Usage

See [documentation](https://eslint-plugin-es.mysticatea.dev/)

## 🚥 Semantic Versioning Policy

This plugin follows [semantic versioning](http://semver.org/) and [ESLint's semantic versioning policy](https://github.com/eslint/eslint#semantic-versioning-policy).

- We will release a new minor version to add new rules when TC39 decided to advance proposals to Stage 4. In the minor releases, we don't update configs.
- We will release a new major version to update configs when new ECMAScript snapshots are available.
