### 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

### Code Explanation:
* First we turn the array to a string, which will give us a string of numbers seperated by a comma, double comma if there was an empty array and literal object text if there was an object, which we can fix it later in our if statement.
* First we turn the array to a string, which will give us a string of numbers separated by a comma, double comma if there was an empty array and literal object text if there was an object, which we can fix later in our if statement.
* We replace the double comma with one, then split it back into an array.
* map through the array and fix object values and convert string numbers to regular numbers.
