Description of functions in Drizzle

Functions
Functions in Drizzle are defined using the def keyword.
def multiply_message(msg: str, times: int = 5) {
    to_print = msg * times
    println(to_print)
}
​
# In this example we show that Drizzle supports default params
multiply_message('a')  # Prints 'aaaaa'
multiply_message('a', 3)  # Prints 'aaa'
Single Line Functions
Drizzle also supports simple one line functions;
def multiply_message(msg: str, times: int = 5) = println(msg * times)
Return Types
Return types of the function are shown through the use of the -> operator
def test() -> int = return 3
If no return type is explicitly described, the null type is assumed to be the return type. The null type is returned from a function in 3 cases: 1. When there's no return statement in the function. 2. When there's an empty return statement in the function. 3. When null is explicitly returned from the function.
