More than 300 powerful ESLint rules

/**
Get all comments in the file, regardless of language. JavaScript/TypeScript expose them via `sourceCode.getAllComments()`, while non-JavaScript languages (for example CSS via `@eslint/css`) expose them on `sourceCode.comments`. Some plugins like `@html-eslint` have `getAllComments()` but it returns `[]` — in that case we fall back to `sourceCode.comments`.

@param {import('eslint').Rule.RuleContext} context
@returns {Array<object>}
