This was a great session, great overview of TypeScript. Even though I'm already using generics and union types for developing Umbraco plugins I've learned that if you add if/else typeof statements for union types TypeScript knows what statement completion it should give to you. Thanks.
Thanks for sharing. I would also recommend Paul Betts: Effective GitHubbing: The GitHub Flow talk available at https://vimeo.com/68378254 as it's the most detailed talk on how Git works under the hood with clear explanations.
