Still Have Questions?

Section titled “Still Have Questions?”

Common questions from TypeScript/JavaScript developers:

Q: “I only know vanilla JavaScript, not TypeScript. Can I still use this?”
A: Yes, but it’ll be harder. Many examples use TypeScript syntax. Consider learning TypeScript basics first.

Q: “I’m a React developer. Is Rust relevant to me?”
A: For React only? Not really. But for WebAssembly, CLI tools, or backend work? Absolutely!

Q: “Will this make me abandon JavaScript?”
A: No! You’ll use both. Rust for performance-critical backend/systems work, TypeScript for everything else.

Q: “Is Rust harder than TypeScript?”
A: Yes, significantly. But this guide makes it easier by relating to what you know.

Q: “How much TypeScript do I need to know?”
A: Basic types, interfaces, generics, async/await. If you’ve shipped a TypeScript app, you’re good.
