Description
In typescript we can specified template at function call
function A<T>(callBack:function(T):void) { }
A<{name:string}>(function(item) { /** item is {name:string} */ })
But I don't know how to force the type of its template when calling it from js file. And I can't find any clue. It seem like not possible so I want to make feature request if it don't have already
