I had a string and I found out it had double line breaks, something like this:

```
A phrase...

Another phrase...

Another phrase...
```

But I wanted it to have online 1 line break in it instead:

```
A phrase...

Another phrase...

Another phrase...
```

Here’s what I did to get the result I wanted:

```javascript
text = text.replace(/[\r\n]{2,}/g, '\n\n')
```
