Question

I notice that when using lambdas:

{
  "name": "Willy",
  "wrapped": function() {
    return function(text) {
      return "<b>" + render(text) + "</b>"
    }
  }
}

a second argument (in addition to text) is passed in. This second argument is a function:

function (template) {
    return render(template, scope);
}

which returns html, given a template (with the inital input json object).

so, if I were to have the lambda as follows:

"wrapped": function() {
  return function(text, func) {
    ....
}

one would expect func("<div>{{name}}</div>") to return html representing a div with the content being filled in with whatever was in the ‘name’ property of the json data object.

HOWEVER, func("{{.}}") does NOT work.
I would expect the object representing the initial input object.

Instead I get the STRING "[object Object]". When I try to use JSON.parse it gives me an ‘Unexpected token o’ error.

The code you are trying to parse as JSON isn’t actually JSON. It’s just a JavaScript object literal. So when you try to put {{.}} into your template, you are rightly getting [object Object] because that is the string representation of the object.
