typescript checking frontend template files

The greatest feature of TypeScript, in terms of big enterprise apps, is type checking. When modifying/extending something low-level, I'll get all errors that arise beneath - just like I would in Java and .Net. But this relates to TS code.

My question is: is it possible to use TypeScript to check types used in frontend templating engines, such as Handlebars, Underscore or [your favourite templating engine]?
I've read that TypeScript 1.6 is gonna support react's JSX, but it's a big limitation to one specific engne only. I guess there is no built-in platform-supported solution, but maybe there is someone who made it work somehow?

Or, in other words, what would you do if you wanted to use TypeScript to check types of variables in handlebars/underscore templates?

首先，查看链接文档中介绍的 TypeScript 1.6 JSX 支持，并将其与所请求的 Handlebars 和 Underscore 模板检查进行比较。issue 未指定文件、入口点或测试；要完成这项工作，需要明确确定模板变量是否可以进行类型检查，以及需要哪些集成工作。
