### elementContains
|
|
|
|
Returns `true` if the `parent` element contains the `child` element, `false` otherwise.
|
|
|
|
Check that `parent` is not the same element as `child`, use `parent.contains(child)` to check if the `parent` element contains the `child` element.
|
|
|
|
```js
|
|
const elementContains = (parent, child) => parent !== child && parent.contains(child);
|
|
```
|
|
|
|
```js
|
|
elementContains(document.querySelector('head'), document.querySelector('title')); // true
|
|
elementContains(document.querySelector('body'), document.querySelector('body')); // false
|
|
```
