# RefArray.make

Creates a new `RefArray` from an array, `Effect`, or `Fx`.

## Signatures

```ts
export declare function make<A, E = never, R = never>(initial: ReadonlyArray<A> | Effect.Effect<ReadonlyArray<A>, E, R> | Fx.Fx<ReadonlyArray<A>, E, R>, eq?: Equivalence<A>): Effect.Effect<RefArray<A, E>, never, R | Scope.Scope>;
```

## Why

Creates array state with equality suited to that Effect data type, so unchanged values do not
produce redundant pushed updates.

## Ownership and lifetime

The creation Effect requires Scope. It owns initializer acquisition, live source subscriptions,
and cleanup; source failures and services stay on reads and pushes.

## Examples

```ts
import { Effect } from "effect"
import * as RefArray from "@typed/fx/RefArray"

// From a plain array
const program1 = Effect.gen(function* () {
  const items = yield* RefArray.make([1, 2, 3])
  const values = yield* items
  console.log(values) // [1, 2, 3]
})

// From an Effect
const program2 = Effect.gen(function* () {
  const items = yield* RefArray.make(
    Effect.succeed(["a", "b", "c"])
  )
  const values = yield* items
  console.log(values) // ["a", "b", "c"]
})
```
