How do you flatten a multidimensional array?

To flatten an array means to reduce the dimensionality of an array. In simpler terms, it means reducing a multidimensional array to a specific dimension. let arr = [[1, 2],[3, 4],[5, 6, 7, 8, 9],[10, 11, 12]]; and we need to return a new flat array with all the elements of the nested arrays in their original order.
