Also remember, that CouchDB uses the Review-Then-Commit (RTC) model
of code collaboration. Positive feedback is represented +1 from
committers
and negative is a -1. The -1 also means veto, and needs to be addressed
to proceed. Once there are no objections, the PR can be merged by a
CouchDB committer.

Artificial Intelligence and Large Language Models Contributions Policy
It is expressly forbidden to contribute material generated by
AI, LLMs, and similar technologies, to the CouchDB project.
This includes, but is not limited to, source code, documentation,
commit messages, or any other areas of the project.

## Overview
There is a typo in
https://docs.couchdb.org/en/stable/partitioned-dbs/index.html:
```
function(doc) {
if(doc._id.indexOf(":sensor-reading-") < 0) {
return;
}
for(var r in doc.readings) {
emit([doc.sensor_id, r[0]], r[1])
}
}
```
The `for...in` loop above assigns indices in `docs.readings` array to
variable `r`: 0, 1, ... n. To iterate over _elements_ in the array, `for...of`
should be written:
```
for(var r of doc.readings) {
emit([doc.sensor_id, r[0]], r[1])
}
```
