title: Find Out Existence of Built-in TypeScript Declarations Using the NPM CLI
body: <p>On the NPM website it is possible to see for each package
  if it provides TypeScript declarations in an @types package (DT icon)
  or if it contains built-in TypeScript declarations (TS icon).</p>
  <p>Is there a way to find out with which of both kinds of package I'm dealing,
  using the NPM CLI, before installing a stub @types package?</p>
