Ways to interpolate template variables inside JavaScript objects
You could JSON.stringify the object, then replace your search value with the actual value, then JSON.parse the result:
function magic(o, a) { var j = JSON.stringify(o); for (var k in a) { j = j.split('${'+k+'}').join(a[k]); } return JSON.parse(j);}
I suggest to you a very simple but very fast and understandable template engine:simple-template.js
