 This tells `ts-jest` (a preprocessor this preset using to transform TS files) to treat JS files the same as TS ones.

+### Observable ... is not a function

+Since v1.0 this preset doesn't import whole `rxjs` library by default for variety of reasons. This may result in breaking your tests that relied on this behavior. It may however become cumbersome to include e.g. `rxjs/add/operator/map` or `rxjs/add/operator/do` for every test, so as a workaround you can include common operators or other necessary imports in your `setupJest.ts` file:
+
+```js
+import 'jest-preset-angular';
+
+// common rxjs imports
+import 'rxjs/add/operator/map';
+import 'rxjs/add/operator/switchMap';
+import 'rxjs/add/operator/do';
+import 'rxjs/add/operator/catch';
+// ...
+
+import './jestGlobalMocks';
