Return values

Functions can return a result using the return keyword:

func add(a, b):
    return a + b

var result = add(2, 3) # result is 5

You can also define the type of the returned value by appending -> ReturnType to the function declaration, it will spit out an error if you try to return something that isn't the correct type.

# Returns integer
func add(a: int, b: int) -> int:
    return a + b

# This won't work
func add(a, b) -> int:
    return "Hello"
