Rewrite your prepend
HTML application to make it use arrays instead of 2 values
and make the function use generics, so that it can handle both strings and
numbers.
In order to allow any value to be entered in your input fields, remove the
type
attribute from the input
tag.
Note: this could be done by using a union type instead of using generics, but the point of the exercise is to practice using arrays and using generics.
