• Changes which React rules are enabled if version 17.0.0 or higher.
  • The react/jsx-uses-react and react/react-in-jsx-scope rules will be disabled if React's version is 17.0.0 and above as they are no longer necessary (see Introducing the New JSX Transform for more information).

• Removes plugins.
  • eslint-plugin-json
    • Replaced by eslint-plugin-jsonc, as eslint-plugin-json uses a non-standard preprocessor (it's using vscode-json-languageservice) and currently returns an empty string, which makes it difficult for other plugins to work alongside of it (see azeemba/eslint-plugin-json#38 for more information). eslint-plugin-jsonc uses the standard ESLint parser espree to create compliant, and thus harmonious, AST.
• Removes rules.
  • eslint/lines-between-class-members
    • Messed with the exceptAfterSingleLine option, but ultimately couldn't find a combination we liked, so we're removing it.
  • jest/prefer-to-be-null
    • Replaced by jest/prefer-to-be.
  • jest/prefer-to-be-undefined
    • Replaced by jest/prefer-to-be.
  • jest/valid-describe
    • Replaced by jest/valid-describe-callback.
