The path so far (2 books)
Why read this first: Once you can write working JavaScript, the anxiety of untyped code at scale comes into view. Programming TypeScript explains from the ground up the idea of layering static types onto JavaScript, providing the entry point to code you can extend safely.
Why read this first: After grasping the overall picture of TypeScript with Boris Cherny's introduction, you solidify a more grounded understanding with a practical Japanese-language primer. 'TypeScript Introduction for Aspiring Professionals' builds carefully from syntax to practical typing, filling in the assumptions an English-language book tends to skip.
