π¨βπΌ Great work with tuples! You now understand:
- π Fixed-length arrays with specific types per position
- π Destructuring to extract tuple values
- β©οΈ Function returns using tuples for multiple values
- βοΈ Tuple vs object tradeoffs
π¦ A common real-world tuple pattern is React's
useState:const [count, setCount] = useState(0)
// Returns [number, function] tuple
This pattern works because the positions are well-defined and the structure is
simple.
