-//! This module helps deno implement timers.
-//!
-//! As an optimization, we want to avoid an expensive calls into rust for every
-//! setTimeout in JavaScript. Thus in //js/timers.ts a data structure is
-//! implemented that calls into Rust for only the smallest timeout.  Thus we
-//! only need to be able to start and cancel a single timer (or Delay, as Tokio
-//! calls it) for an entire Isolate. This is what is implemented here.
