The `mode()` function computes the mode or value that occurs most often in a
specified column in the input table.
_`mode()` is an [aggregate function](/flux/v0.x/function-types/#aggregates)._

```js
mode(column: "_value")
```

If there are multiple modes, it returns all of them in a sorted table.
Mode only considers non-null values.
If there is no mode, `mode()` returns `null`.
