👉 "Unnestled" is a phrase that refers to something being structured in such a way that it has no gaps or overlaps. For example, if you have an array of numbers and you want to nest them like this: ``` let numbers = [1, 2, 3]; ``` Then the nested structure would be `numbers[0]`, `numbers[1]`, and `numbers[2]`. The order of the elements in each level is not important.
