python string formatting in JavaScript [duplicate]

Question

Is there a another way to do this? I'm using the underscore js lib here, which is where the _. comes from. I'm used to this sort of procedure to format strings in python and I'd like something simple for JavaScript without doing + + + + all the time. This works, but it feels like I reinvented the wheel.

function foo (iterable, string) {
  var s = iterable.shift();
  string = string.replace("%s",s);
  return _.isEmpty(iterable) ? string : foo(iterable,string);
};

foo(['sam','green','ham'],"%s likes %s eggs and %s.");
"sam likes green eggs and ham."

try out the sprintf lib, specifically vsprintf.

vsprintf('The first 4 letters of the english alphabet are: %s, %s, %s and %s', ['a', 'b', 'c', 'd']);
