Bug: `capitalized-comments` yelling about an inline comment

See original GitHub issue

Tell us about your environment

Environment Info:

Node version: v14.0.0
npm version: v6.14.4
Local ESLint version: v6.8.0 (Currently used)
Global ESLint version: Not found

What parser (default, Babel-ESLint, etc.) are you using? @typescript-eslint/parser

Please show your full configuration:

Configuration

module.exports = {
  root: true,

  parser: '@typescript-eslint/parser', // Make ESLint compatible with TypeScript
  parserOptions: {
    // Enable linting rules with type information from our tsconfig
    tsconfigRootDir: __dirname,
    project: ['./tsconfig.eslint.json'],

    sourceType: 'module', // Allow the use of imports / ES modules

    ecmaFeatures: {
      impliedStrict: true, // Enable global strict mode
    },
  },

  // Specify global variables that are predefined
  env: {
    node: true, // Enable node global variables & Node.js scoping
    es2020: true, // Add all ECMAScript 2020 globals and automatically set the ecmaVersion parser option to ES2020
  },

  plugins: [
  ],

  extends: [
    '@xpring-eng/eslint-config-base',
  ],
  rules: {},
  overrides: [],
}

What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

const example = {
  nonce: 'abc', // a numeric string
}

eslint . --ext .ts

What did you expect to happen? I expected to not get a warning on an uncapitalized inline comment.

What actually happened? Please include the actual, raw output from ESLint.

  55:7   warning  Variable 'example' is declared but its value is never read. Allowed unused names must match /^_/  @typescript-eslint/no-unused-vars-experimental
  55:7   warning  'example' is assigned a value but never used. Allowed unused vars must match /^_/u                @typescript-eslint/no-unused-vars
  56:17  warning  Comments should not begin with a lowercase character                                              capitalized-comments
