Feature Request: Map Command about _hyperscript

[dz4k]

This could be part of a LINQ-like feature in hyperscript:

from record in result.data index i select 
`<tr>
    <td>Record #${i + 1}</td>
    <td>${record.firstName}</td>
    <td>${record.lastName}</td>
    <td>${record.emailAddress}</td>
</tr>`

Interesting idea. I checked out the LINQ link. It seems like a flavor of SQL. This map command feels like a gateway into a lot of interesting, related features. If working with sets is important, we could easily justify several set-based commands like:

Command	Example
filter	filter it where record.firstName is not null
sort	sort it alphabetically by firstName
join	join it to <p.queryable /> on record.firstName == @firstName
group	as in group it by record.category

Crazy example:

fetch /my-server as json
filter it where record.firstName is not null
sort it alphabetically by firstName
map it using #myTemplate
put it into #my-table
