TypeScript and JavaScript keywords

While learning TypeScript -- an ongoing process -- I sometimes struggle to find the canonical docs in the Handbook. So today, I asked grok to generate a list of TypeScript and JavaScript keywords and links to their docs.

Thank you all MDN and TypeScript contributors. 🙏
