Creates an array from an async iterable.

import { toArray } from "./collections.ts";

async function* gen() { yield "foo"; yield "bar"; yield "baz"; }
const array = await toArray(gen());

The array variable will be an array like ["foo", "bar", "baz"].

Note that its first parameter is assumed to be finite; otherwise, it will never return. The following example will never return:

import { toArray } from "./collections.ts";
import { count } from "./infinite.ts";

await toArray(count(0));
