 ### Code Explanation:
 
 *   Create a new variable to keep flattened arrays.
-*   Create a function that will add non array elements to the new variable, and for the ones that are array it loops through them to get the element.
-*   It does that by using recursion, if the element is an array then call the function again with a layer of array deeper to check if it is an array or not. if it is not then push that non-array element to the variable that gets returned. Otherwise, keep going deeper.
-*   Invoke the function, the first time you will always pass it an array, so it always fall in to the isArray branch
