lib es6 loses window and other dom stuff

[basarat]

ts:

console.log(window);

tsconfig.json:

{
  "compilerOptions": {
    "lib": [
      "es6"
    ]
  }
}

compile:

tsc -p .

Expected behavior:
Works!

Actual behavior:
Error cannot find name window.

you have to choose it. so

{
  "compilerOptions": {
    "lib": [
      "es6",
      "dom"
    ]
  }
}

here are more details:

• es6/es5/es2015/es2016/es2017 -- built in JS definitions.
• dom -- DOM definitions
• webworkers -- Web worker definitions
• scripthost -- widows Script Host

Thanks for that. I've fixed up my understanding / code etc. Also mentioned it here : https://basarat.gitbooks.io/typescript/content/docs/types/lib.d.ts.html#lib-option

Minor: the link https://github.com/Microsoft/TypeScript/wiki/What's-new-in-TypeScript#including-built-in-type-declarations-with---lib mentions DOM if you are working on a node project using --lib es5,es6. Having a look at the code es6 automatically references es5 (as seen here) so really it should be just --lib es6.

That said I'd PR but it seems its not linked to the page here : https://github.com/Microsoft/TypeScript-wiki/blob/master/What's-new-in-TypeScript.md 🌹
