Introduction to TypeScript for devs without JS experience? (feddit.de)

Can anyone recommend a good introduction/book to TypeScript for people who already know some programming (e.g. Java, Python) but have no experience with JavaScript?

The only texts I've found so far assume prior JS knowledge (like The TypeScript Handbook https://www.typescriptlang.org/docs/handbook/intro.html) or seem rather unstructured to me (e.g. dropping a lot of different ways and shortcuts to do things without explaining concepts or making no clear distinction between basics/best practices and advanced use cases/edge cases).

Ideally it would explain core concepts (like functions, types, classes, ...) first, with their most common use cases. Later chapter would do deep dives into different topics.

Edit: when I'm talking about TypeScript I'm talking about the whole language, not just the "modifications" it makes to JavaScript.

Yes, and I would like to learn the tightened up version rightaway ;-) When I want to learn e.g. about functions, I want to have a chapter "Fundamentals of functions" or something (and probably another chapter for advanced stuff about functions, edge cases etc.). Right now it seems like I would have to first read about functions in a JS book without knowing how they will be used best in TS). And then I would take another book and read about the modifications that TS makes to them.

I get that in order to "fully understand" TS I need to "fully understand" JS. But in the beginning I would like something that explains the core concepts of TS (which of course may and often will include JS concepts).
