How to replace question marks inside a string with the values of an array?

Question

Given the string 'Hello ?, welcome to ?' and the array ['foo', 'bar'], how do I get the string 'Hello foo, welcome to bar' in a single line of code with JavaScript (possibly with jQuery, Underscore, etc.)?

Answer 1

var s = 'Hello ?, welcome to ?';
var a = ['foo', 'bar'];
var i = 0;
alert(s.replace(/\?/g,function(){return a[i++]}));
