Demo: Benchmarking Exceptions
We show a live benchmark comparing dictionary lookups with exception-based KeyNotFoundException handling versus ContainsKey checks, and Parse versus TryParse for string-to-integer conversion. The lesson shows concrete timing numbers illustrating that exception-throwing code can be 50-1000x slower than the TryParse equivalent.
