Function Definition

Define a function using the fn keyword.

fn greet(name) {
    pt("Hello, " + name + "!")
}

greet("Zaky")

Anonymous Functions (Arrow Syntax)

dryLang does not support traditional anonymous functions (like fn() {}). Instead, we strictly enforce "one way to do things" using Arrow Functions (->).

// Single parameter
double = x -> x * 2

// Multiple parameters
add = (a, b) -> a + b

// Block body
complex_math = (x, y) -> {
    z = x + y
    rev z * 2
}

Returning Values

Use rev to return a value from a function.

fn add(a, b) {
    rev a + b
}

result = add(10, 20)
pt(result) // 30

Async Functions

Use asn fn to declare an async function, and awt to await it.

asn fn fetchData() {
    rev req("https://api.example.com")
}

data = awt fetchData()
