Javascript - String replace by multiple strings

Question

I'm wondering if a function exists that does this thing:

var greetings = "Hello %s, I'm %s"
greeting.replace('Mickey','Minnie');

// Should return: Hello Mickey, I'm Minnie

EDIT

Thank you all for the help!

I created a little node package for it, in case anyone needed something like this:

You can use template literals in an IIFE:

const greetings = ((a, b) => `Hello ${a}, I'm ${b}`)('Mickey','Minnie');

console.log(greetings);

If you're not able to use ES6 (template literals) or a polyfill, you can also pass a function to .replace().

See:

var greeting = "Hello %s, I'm %s"
var replacements = ['Mickey', 'Minnie'];

greeting.replace(/%s/g, function() {
  return replacements.shift();
});

This returns "Hello Mickey, I'm Minnie"

Using just "traditional" Javascript:

var greetings = "Hello %s, I'm %s"
(['Mickey','Minnie']).forEach (function (n) { greetings = greetings.replace ('%s', n) });
