21,679,677 | I have a grid presenting people. Their names with a picture. The name must be displayed on 2 line. First name on the first line and surname on second one.
**I can't change the html** (I would use `<br/>` tag and it would be solved).
I need to find a way (CSS prefered) to achieve this.

* Use the [fs module](https://nodejs.org/api/fs.html) to read you JSON files
* Call `JSON.parse()` to parse the raw JSON
* Choose the file according to `var lang = req.params.lang` using some kind of logic (for example, `'spanish' -> './data/spanish.json'`)

Just use `res.json({key: value , key2: value2})` instead of `res.send`
In your case, you can
```
const language = req.params.lang;
res.json({lang: lang})
```
you will receive a JSON object instead of text |
310,319 | I was wondering if the [canonical commutation relations](http://en.wikipedia.org/wiki/Canonical_commutation_relation) have any connection to geometry?
