Struct boa::syntax::ast::node::return_smt::Return

pub struct Return { /* fields omitted */ }

The return statement ends function execution and specifies a value to be returned to the function caller.

Syntax: return [expression];

expression:

The expression whose value is to be returned. If omitted, undefined is returned instead.

When a return statement is used in a function body, the execution of the function is stopped. If specified, a given value is returned to the function caller.
