Functions

Functions are first-class citizens in KodiScript. Use the fn keyword to define them.

Syntax

let add = fn(x, y) {
    return x + y
}

Functions capture variables from their surrounding scope:

let makeAdder = fn(x) {
    return fn(y) {
        return x + y
    }
}
 
let addTwo = makeAdder(2)
print(addTwo(3)) // Output: 5

You can pass functions as arguments:

let apply = fn(f, val) {
    return f(val)
}
 
let double = fn(x) { x * 2 }
 
print(apply(double, 10)) // Output: 20
