title: Where can I find documentation for TypeScript's built-in types and standard library?
body: <p>I love working with TypesScript (as a former C# dev) and I spend hours every month browsing through the online <a href="https://www.typescriptlang.org/docs/home.html" rel="noreferrer">documentation</a>.</p>
  
  <p>However, I can't seem to find documentation about built-in types such as <code>Map&lt;T1,T2&gt;</code>, etc.</p>
  
  <p>The documentation refers to the <em>standard library</em> in a few places, but I also cannot seem to find documentation for that (for example, the <code>Partial&lt;T&gt;</code> awesome class.</p>
  
  <p>Am I just missing it?</p>
