 ### trim
 
 By default, whitespace is preserved:
 
-```js
+```ts
 parse('<br>\n'); // [React.createElement('br'), '\n']
 ```
 
 But certain elements like `<table>` will strip out invalid whitespace:
 
-```js
+```ts
 parse('<table>\n</table>'); // React.createElement('table')
 ```
 
 To remove whitespace, enable the `trim` option:
 
-```js
+```ts
 parse('<br>\n', { trim: true }); // React.createElement('br')

 However, intentional whitespace may be stripped out:
 
-```js
