The extensive adoption of JavaScript for application development, and the ability to use HTML and JavaScript to create Windows Store apps, has made JavaScript a vital part of the Windows development ecosystem. Microsoft has done extensive work to make JavaScript easier to use. Microsoft's TypeScript extends many familiar features of .NET programming to JavaScript. With TypeScript Succinctly by Steve Fenton, you will learn how TypeScript provides optional static typing and classes to JavaScript development, how to create and load modules, and how to work with existing JavaScript libraries through ambient declarations. TypeScript is even significantly integrated with Visual Studio to provide the autocompletion and type checking you are most comfortable with.

He has written books on TypeScript, Octopus Deploy, and Web Operations Monitoring.
Partially outdated now, and TypeScript specific parts are mixed with es6. Otherwise good short intro. Surprisingly big part was about the unit testing in TypeScript.
Without jumping into too much detail, the book gives a little introduction to TypeScript, without the whole bullshit other books like to add. So it is that I probably highlighted the whole thing.
Don't expect to go deep into TypeScript and all its nuances, though.
