title: Disable ESLint that create-react-app provides
body: <p><a href="https://github.com/facebook/create-react-app/blob/master/CHANGELOG.md" rel="noreferrer"><code>create-react-app</code> v3.0.0 is out</a>. It supports TypeScript linting internally. (That's nice!) I think I understand the situation where TSLint is on, and am planning to replace it with ESLint, but it is not right now.</p>
  <p>How to disable that linting step in <code>react-scripts start</code>?</p>
  <p><code>/* eslint-disable */</code> and others are not the ones I'm looking for.</p>
