Composable Concurrency Tasks
summary
Claims that Ember Concurrency uses ES6 generators to make async code concise and cancelable are demonstrated with concrete examples: generator-based tasks yield intermediate promises so later steps don’t run, removing need for isDestroyed checks. A reusable progress task helper is built by wrapping task functions; tests gain reliability via ember-concurrency-test-waiter; retry logic and exponential backoff arrive through ember-concurrency-retryable. Demos and unit tests run and show cancellation, test waiting, and retry schedules working as described.
