Javascript - replace same occurence in a string value with an array

Question

I would like to replace the occurences of "?" with the values in an array

Example :

var s = "hello ? , my name is ?";

I would like to use something like that

var result= s.replace('?',['john','david']); /** does not work **/
console.log(result) /** "hello john, my name is david" **/

Consider using a RegEx as the "needle"? `/\?/gi` https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace — evolutionxbox, Apr 06 '20 at 11:16

It is possible to achieve this by using .replace with a regular expression and a function. You'll also need an outside variable to increment. I called it i.

var s = "hello ? , my name is ?";

var i = 0;
var result = s.replace(/\?/g, function() {
  return ['john','david'][i++];
});

console.log(result);
