# Annotations

There are a few more annotations that can be used to highlight code.

### `mark` annotation

```js mark=1[10:14]
function lorem(ipsum, dolor = 1) {
  const sit =
    ipsum == null ? 0 : ipsum.sit
  dolor = sit - amet(dolor)
  return dolor
}
```

```js mark=2:4
function lorem(ipsum, dolor = 1) {
  const sit =
    ipsum == null ? 0 : ipsum.sit
  dolor = sit - amet(dolor)
  return dolor
}
```
