  console.log('Hello');
}

ESLint Config

  parser: "@typescript-eslint/parser",
  rules: {
    "@typescript-eslint/naming-convention": [
      "error",
      {
        selector: 'default',
        format: ['camelCase'],
        leadingUnderscore: 'forbid',
        trailingUnderscore: 'forbid'
      },
      {
        selector: 'function',
        format: ['camelCase', 'PascalCase'
        ]
      }
    ]
  },
};

tsconfig

{
  "compilerOptions": {
    "strict": true,
    "erasableSyntaxOnly": true
  }
}

Expected Result

I expect that the function cannot be named HELLO. Acceptable names are either hello or Hello.

Actual Result

The function is allowed to be named HELLO.
