ES2024 Introduces Promise.withResolvers to Simplify Deferred Promise Patterns

JavaScript developers have long used a workaround of leaking resolve and reject functions out of the Promise constructor to control resolution from external event listeners or callbacks. ES2024 introduced Promise.withResolvers, a static method that returns the promise, resolve, and reject as a plain object, eliminating the need for that closure escape pattern. The new API produces identical runtime behavior to the old approach, including the same microtask timing and error propagation, but makes the intent of creating a deferred Promise explicit. Common use cases include wrapping event-based APIs, building async queues where producers and consumers are decoupled, and batching operations where multiple callers await a single shared resolution. The change reduces multi-line boilerplate to a single destructuring call, making code easier to read and reason about.
