The syntax is similar to @param tag, examples from [documentation](http://usejsdoc.org/tags-returns.html):

```javascript
/**
 * Returns the sum of a and b
 * @param {Number} a
 * @param {Number} b
 * @returns {Number}
 */
function sum(a, b) {
    return a + b;
}
```

or

```javascript
/**
 * Returns the sum of a and b
 * @param {Number} a
 * @param {Number} b
 * @returns {Number} Sum of a and b
 */
function sum(a, b) {
    return a + b;
}
```
