Question

You asked an AI assistant for a TypeScript function to compute the median latency from an array of millisecond samples, for a metrics dashboard. It produced:

typescript

1function median(samples: number[]): number {2  samples.sort((a, b) => a - b);3  const mid = Math.floor(samples.length / 2);4  return samples[mid];5}

It returns 30 for `[10, 20, 30, 40, 50]`. What are the correctness and side-effect bugs?

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
