Display logs only for development tests.

How to display logs in browser console, only for development tests?

var myapp = myapp || {};
myapp.logs = {};

myapp.logs.log = function(message) {
  if (document.URL.indexOf('dev.') != -1) {
    console.log(message);
  }
}

You can do the same with myapp.logs.info, myapp.logs.warn, myapp.logs.error ;)
