// Array#reduce + recursion to flatten
// any level of nested arrays

// So we reduce the nested array and aggregate the values of the Integer type into the seed array
// during the aggregation we 1st check if the values from the input array are of the Array type via `isArray`
// if so we call the function `flatten` again passing that array value as input and if the value is 
// not of the Array type it we `concat` the value with the seed array
// below is a timeline of how the values look after the input array is given
// [[1, 2, [3]], 4]: --- [1,2,[3]] --> 1 --> 2 --> [3] --> 3 --> 4
