[−][src]Struct boa::syntax::ast::node::return_smt::Return
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.
