Struct boa::syntax::ast::node::FormalParameter

pub struct FormalParameter {
    pub name: String,
    pub init: Option<Box<Node>>,
    pub is_rest_param: bool,
}

"Formal parameter" is a fancy way of saying "function parameter".

In the declaration of a function, the parameters must be identifiers, not any value like numbers, strings, or objects.

function foo(formalParametar1, formalParametar2) {
}
