<A = never>(n: number): Array<A | undefined>Creates a new Array of the specified length with all slots uninitialized.
When to use
Use when you need a pre-sized array that will be filled imperatively.
Details
Elements are typed as A | undefined because the slots are empty.
Example (Allocating a fixed-size array)
import { Array } from "effect"
const result = Array.allocate<number>(3)
console.log(result.length) // 3constructorsmakeBy
