@sinonjs/fake-timers provides a powerful and flexible way to manipulate time in JavaScript tests. It meticulously simulates the behavior of setTimeout, setInterval, Date, nextTick, queueMicrotask, requestAnimationFrame, and clearImmediate while preserving the original implementations. This package allows for precise control over timing-related logic, simplifying testing of asynchronous code without relying on real-time delays. It is a crucial tool for improving test speed, reliability, and determinism in projects that deal with asynchronous events.
