string of the form "to=from & to=eval & to & ... & !where=eval"
hash of the form {to: from, ...}
callback of the form (idx,array) => { ... }

The "!where" clause returns only records having a nonzero eval.

Kind: inner method of Array
Returns: Object - Aggregated data

| Param | Type | Description |
| --- | --- | --- |
| index | String \| Object \| function | Indexer |
| ctx | Object | Context of functions etc |

Example
``js
[{x:1,y:2},{x:10,y:20}].$("u=x+1&v=sin(y)&!where=x>5",Math)
{ u: [ 11 ], v: [ 0.9129452507276277 ] }
