|
```js

|
const body = $("body");
|
|
const div1 = $("div", body);
|
|
```
|
|
|
|
### `$$(selector, [rootElement])`
|
|
|
|
Selects all matching elements (or an empty `NodeList`):
|
|
|
|
```js
|
|
const head = $('head');
|
|
const stylesheets = $$('link[rel="stylesheet"]', head).map(console.log);
|
|
```
