node.js - which javascript template engine is nest suited to generate JSON -

both mustache , handlebars awesome. them both individual simplicity , excellence. mustache because it's 1 template works in lots of places , handlebars because provides few more features.

the challenge have seem have been implemented output html or other document structure tags in pairs , there no separators.

to further clarify, if have array of items output in list works well:

<ul>    {{#each items}}    <li>{{name}}</li>    {{/each}} </ul> 

this works great. if want output json-like:

[    {{#each items}}        { name:{{name}} }    {{/each}} ] 

this not work because json requires there commas separating items in list. , cannot put comma after innermost '}' because cause error too.

there several posts/recommendations people have requested optional separator attribute added #each or adding #join. 1 committer said should implemented plug-in because core needs simple.

the politics aside. being able format javascript object json string seems suited templates.

**one final idea. there may better javascript idiom reformating javascript object. suppose interesting consider.

ps: 1 reason template because becomes self documenting.

update:

@kevin on @ handlebarsjs team able create "helper" function implemented feature missing. it's not make core time code worked:

[    {{#join items sep=','}}        { name:{{name}} }    {{/join}} ]
