Function

Represents a callable object. Functions are prefixed with right arrow operator (->). They are anonymous and cannot have a named unlike other programming languages. They are invoked using call operator. They can take in parameters and may return values.

Functions can marked as async to allow usage of .await. These functions always return a unawaited value. The async function is not executed until .await is invoked.

Syntax

-> [async] [param1, param2, ..., paramN] {
    statements
}

-> [async] [param1, param2, ..., paramN] : expr

Example

-> { return 1; }
-> a, b { return a + b; }

-> a, b : a + b
-> x : x

-> async { return 1; }
-> async a, b { return a + b; }

-> async a, b : a + b
-> async x : x

Properties

call

Calls the function and returns the result.

Signature

-> List<Any> params : Any

Signature (Async Function)

-> List<Any> params : Unawaited<Any>

Example

printHello := -> value {
    print(value);
};

printHelloAsync := -> async value {
    print(value);
};

# prints "Hello World!"
printHello.call(["Hello World!"]);

# prints "Hello World!"
printHelloAsync.call(["Hello World!"]).await;
