Why it matters
The article explains Big O Notation in practical terms for TypeScript/JavaScript developers, focusing on how code performance scales with data growth. It illustrates common pitfalls like O(n²) nested loops and demonstrates optimization techniques such as using Sets for O(1) lookups and binary search for O(log n) efficiency, emphasizing the space-time tradeoff as a core optimization principle.
