The second array to union / 第二个数组

The array with duplicates removed / 去重后的数组
unionBy([1, 2, 3], [2, 4, 5, 6], (item) => item % 2) // => [1, 2]unionBy([1, 2], [3, 4], (item) => item % 2) // => [1, 2] Copy
unionBy([1, 2, 3], [2, 4, 5, 6], (item) => item % 2) // => [1, 2]unionBy([1, 2], [3, 4], (item) => item % 2) // => [1, 2]
