(duration: Duration.Input): Effect<void>Returns an effect that suspends the current fiber for the specified duration without blocking a JavaScript thread.
Example (Pausing without blocking)
import { Console, Effect } from "effect"
const program = Effect.gen(function*() {
yield* Console.log("Start")
yield* Effect.sleep("2 seconds")
yield* Console.log("End")
})
Effect.runFork(program)
// Output: "Start" (immediately)
// Output: "End" (after 2 seconds)export const const sleep: (
duration: Duration.Input
) => Effect<void>
Returns an effect that suspends the current fiber for the specified duration
without blocking a JavaScript thread.

sleep: (duration: Duration.Inputduration: import DurationDuration.type Duration.Input = /*unresolved*/ anyInput) => interface Effect<out A, out E = never, out R = never>The Effect interface defines a value that lazily describes a workflow or
job. The workflow requires some context R, and may fail with an error of
type E, or succeed with a value of type A.
When to use
Use when you need to represent a lazy, composable workflow that can require
services, fail with a typed error, or succeed with a typed value.
Details
Effect values model resourceful interaction with the outside world,
including synchronous, asynchronous, concurrent, and parallel interaction.
They use a fiber-based concurrency model, with built-in support for
scheduling, fine-grained interruption, structured concurrency, and high
scalability.
To run an Effect value, you need a Runtime, which is a type that is
capable of executing Effect values.
