I forked [Formatting toolbar](https://meta.discourse.org/t/formatting-toolbar/40649) to add some very custom formatting stuff.
It has [discourse-formatting-toolbar/assets/javascripts/lib/discourse-markdown/formatting\_bbcode.js at master · MonDiscourse/discourse-formatting-toolbar · GitHub](https://github.com/MonDiscourse/discourse-formatting-toolbar/blob/master/assets/javascripts/lib/discourse-markdown/formatting_bbcode.js#L1-L6)
My code looks like this:
```javascript
function replaceTitle(text) {
while (
text !==
(text = text.replace(/\[title\](.+?)\[\/title\]/gi, function (match, p) {
return `${p}
`;
}))
);
return text;
}
```
But `eslint` complains:
```
9:3 error Expected { after 'while' condition curly
```
I tried moving that `while` and stuff after it onto a single line (the formatting here is applied by vscode and usually works with the other plugins I manage), but that didn’t help either.
Can someone provide me with a clue?
EDIT: Well, it turns out that I don’t actually need that function, but I would still like to know what the problem is.

The reason for the eslint warning is that you need curly braces surrounding your `return text`;
That is, it should look like so:
```js
while (
text !==
(text = text.replace(/\[title\](.+?)\[\/title\]/gi, function (match, p) {
return `${p}
`;
}))
) {
return text;
}
```
Although JavaScript allows for the omission of the curly braces, ESLint enforces the consistent curly brace style.
