Function Declaration: Default Value

[staycoolcall911]

The default value notation (= y) may appear in declarations of struct fields, class fields or function arguments.

The following sections of the language reference should mention the default value notation:

3. 1.6.1.4 Function arguments (under 1.6 optionality):

Alternatively, using the default value notation can be used to allow a parameter not to be assigned
when calling the function. Using a default value in the function declaration ensures that by
always has a value so there is no need to unwrap it (this is why its type is num and not num?):

let increment = (x: num, by: num = 1): num {
  return x + by;
}

4. 1.7 Type Inference

Function argument type is inferred iff a default value is provided.
