Problem

I am using Angular (version 2) with TypeScript (version 1.6) and when I compile the code I get these errors:

```

Solution

A known issue: https://github.com/angular/angular/issues/4902

Core reason: the .d.ts file implicitly included by TypeScript varies with the compile target, so one needs to have more ambient declarations when targeting es5 even if things are actually present in the runtimes (e.g. chrome). More on lib.d.ts
