My vote will be for Javascript if it was there .
Its the most dynamic versatile language i have ever used.
You can code in functional style (Closures, Functions as first class citizens) or Object Oriented style (Classes, Inheritance ) whichever you prefer.
You have loose type checking native-ly but can move to strict type checking using subsets such as Typescript.
Its one of the most amazing language invented so far. It never misses to surprise you whenever you try to go deep.
