There is one significant change with TS 2.2, you don't have to use type definitions for libraries anymore. Since all JavaScript is valid TypeScript. With out of the box setup the import from library that has no type definitions, works just fine. It returns `any` type, so you can use all libraries just like you would in JavaScript. So if you ram your head against bad type definition of a module, just delete it and continue using it like you would in normal JS.
