A playful deep-dive into advanced TypeScript type system tricks with no practical production intent. Covers: using string literal unions with `string & {}` for autocomplete hints, extracting Mustache template variables via recursive template literal types, mapping tuple arrays to typed objects using mapped types and `Extract`, and implementing boolean logic gates and even a 1-bit full adder entirely within the type system. Includes a warning that complex type computations (like an 8-bit ALU) can take 30 seconds to resolve.
