Answer
Use .catch() with promises and try/catch with async/await.
Quick Answer
In async JS, errors surface as Promise rejections. Unhandled: .catch() at the end of a chain handles any rejection above it. async/await: use try/catch. Promise.all rejects if any sub-promise rejects — use Promise.allSettled to get all results regardless. Always handle rejections — unhandled ones throw warnings (or errors in Node.js 15+).
