I might be taking a course in Computer Science at a Uni soon, what languages are commonly used @ Computer Science?

Functional programming, eh?

For example, if you want to change every element in an array:
array.map! do |elem|
    elem * 10
end
If you want to summarize every element in an array:
sum = array.shurg_dunno_lol(memory => 0) do |elem, memory|
    memory += elem
end
