Error Handling in Async Code

What error handling threshold pattern is implemented?

class AsyncOperationQueue {
  constructor() {
    this.errors = [];
    this.results = [];
  }

  async addOperation(operation) {
    try {
      const result = await operation();
      this.results.push(result);
    } catch (error) {
      this.errors.push(error);
      if (this.errors.length >= 3) {
        throw new AggregateError(this.errors, 'Too many operations failed');
      }
    }
  }
}

Simple error collection
Error transformation
Error threshold with aggregation
This implements an error threshold pattern: 1) Collects errors until a threshold is reached, 2) Uses AggregateError to combine multiple errors, 3) Allows some failures before total failure, 4) Maintains error history, 5) Useful for batch operations with tolerance for some failures, 6) Common in resilient systems that can handle partial failures.
