Use Rust for systems-level performance and memory safety, and TypeScript for rapid web development and broad ecosystem compatibility. Rust compiles to native code with zero-cost abstractions, while TypeScript compiles to JavaScript for browser and Node.js environments. Choose Rust when you need low-level control, concurrency, or embedded capabilities; choose TypeScript when building web applications, APIs, or when leveraging existing JavaScript libraries. ```bash

Initialize a new Rust project for systems work

cargo new my_rust_app --bin

Initialize a new TypeScript project for web work

npm init -y && npm install typescript && npx tsc --init

Rust is like building a custom engine for a race car: it's fast, safe, and gives you total control, but requires more expertise to build. TypeScript is like using a reliable, pre-built car chassis for a delivery service: it's easier to set up, works everywhere, and has tons of parts available, but you're limited to the road it was designed for. Use Rust when performance and safety are critical; use TypeScript when you need to ship web features quickly.
