# Attributes

Attributes define a set of properties on source code elements.

```js
Attributes             = { Attribute } .
Attribute              = "@" identifier AttributeParameters .
AttributeParameters    = "(" [ AttributeParameterList [ "," ] ] ")" .
AttributeParameterList = AttributeParameter { "," AttributeParameter } .
AttributeParameter     = PrimaryExpression
```

The runtime specifies the set of defined attributes and their meaning.

##### Example attributes

```js
@edition("2022.1")
package main
```
