## Lookbehind
```warn header="Lookbehind browser compatibility"
Please Note: Lookbehind is not supported in non-V8 browsers, such as Safari, Internet Explorer.
```
Lookahead allows to add a condition for "what follows".
Lookbehind is similar, but it looks behind. That is, it allows to match a pattern only if there's something before it.
