Sort the Unsortable

In this challenge you will be given an array similar to the following:

[[3], 4, [2], [5], 1, 6]

In words, elements of the array are either an integer or an array containing a single integer. We humans can clearly see that this array can reasonably be sorted according to "the content of the elements" as:

[1, [2], [3], 4, [5], 6]

Create a function that, given an array similar to the above, sorts the array according to the "content of the elements".

Examples

sortIt([4, 1, 3]) ➞ [1, 3, 4]

sortIt([[4], [1], [3]]) ➞ [[1], [3], [4]]

sortIt([4, [1], 3]) ➞ [[1], 3, 4]

sortIt([[4], 1, [3]]) ➞ [1, [3], [4]]

sortIt([[3], 4, [2], [5], 1, 6]) ➞ [1, [2], [3], 4, [5], 6]

Notes

To reiterate, elements of the array will be either integers or arrays with a single integer.
