AggregateError efficiently bundles multiple errors into a single error object. This simplifies error handling when asynchronous operations or concurrent tasks might produce multiple failures. It follows the AggregateError specification, providing properties like errors to inspect individual thrown errors. Use it to collect errors, prevent early termination, and report grouped failures neatly. AggregateError improves error clarity and makes debugging multi-error scenarios easier in JavaScript projects.
