(finalizerStrategy?: "sequential" | "parallel"): Effect<Closeable>Creates a new Scope with the specified finalizer strategy.
Example (Creating a scope)
import { Console, Effect, Exit, Scope } from "effect"
const program = Effect.gen(function*() {
// Create a scope with sequential cleanup
const scope = yield* Scope.make("sequential")
// Add finalizers
yield* Scope.addFinalizer(scope, Console.log("Cleanup 1"))
yield* Scope.addFinalizer(scope, Console.log("Cleanup 2"))
// Close the scope (finalizers run in reverse order)
yield* Scope.close(scope, Exit.void)
// Output: "Cleanup 2", then "Cleanup 1"
})export const const make: (
finalizerStrategy?: "sequential" | "parallel"
) => Effect<Closeable>

make: (finalizerStrategy: "sequential" | "parallel" | undefinedfinalizerStrategy?: "sequential" | "parallel") => 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.
