copyWithIn() with Array-like #20
Description
Currently, following behavior.
import { copyWithin } from "@immutable-array/copyWithin";
const arrayLike = { length: 5, 3: 1 };
let actual = copyWithin(arrayLike, 0, 3);
assert.deepStrictEqual(actual, [1, , , 1,]);Native Array#copyWithIn() work following:
[].copyWithin.call({length: 5, 3: 1}, 0, 3);
// {0: 1, 3: 1, length: 5}It return just array-like object.
Is this no problem?
