## 6.2.3. Parenthesized Forms
|
|
|
|
A parenthesized form is an optional list of expressions enclosed in parentheses:
|
|
|
|
```javascript
|
|
parenth_form ::= "(" [starred_expression] ")"
|
|
```
|
|
|
|
A parenthesized expression produces whatever the expression list produces: if the list contains at least one comma, it produces a tuple; otherwise, it produces the single expression that makes up the list of expressions.
