Make one gsub call instead of five

Question

How can I replace this: ``` lyrics = lyrics.gsub(/\n/,'').gsub(/^\{"similar": $$/, '').gsub(/$$\}$/, '').gsub(/^\{/, '').gsub(/\}$/, '') ``` to something shorter and one gsub call?

Accepted Answer

You can joint multiple regexes into one by using alternate symbol `|` and creating branches in regex. Pay attention to anchors like `^`, `$` and other, because if they appear in one branch, they only work for that branch, not whole regex

```
lyrics = lyrics.gsub(/\n|^\{"similar": $$|$$\}$|^\{|\}$/, '')
```
