After upgrading to beta 6 I started getting error messages when transpiling from TypeScript to ES5. It seem to affect ES6 methods of Array. One example would be:

xxxxx.ts(347,49): error TS2339: Property 'findIndex' does not exist on type 'Xxxxxx[]'.

I was getting more errors until I added ///<reference path="../../node_modules/angular2/typings/browser.d.ts"/> at the top of the .ts file doing bootstrapping.

Check the Angular2 GitHub issues https://github.com/angular/angular

I did see your link, thank you. I didn't find this issue addressed there. Is there a more specific link that you could share?

It seems that all that is necessary here is to add typing for es6 shim. The change log for beta 6 says "... If you rely on es6 APIs other than Promises and Collections, you will need to install the es6-shim typing instead of using the tag above." The question is: where to get the es6-shim typing?

Solved.

Go to https://github.com/DefinitelyTyped/DefinitelyTyped/blob/ffceea9dd124d277c4597c7bd12930666ec074c5/es6-shim/es6-shim.d.ts and download the es6-shim.d.ts file. Then add reference to this file (and remove reference to node_modules/angular2/typings/browser.d.ts).
