Javascript String Question 8

Introduction

Create a function to find the index of the first unique character in a string.

Example: "mom" o is the first unique, and it is at index 1. 

var x = "mom";

function indentifier(string) {
  //your code here
}
console.log(indentifier(x));



var x = "mom";

function indentifier(string) {
  var obj = {};

  for(var i=0; i<string.length; i++){
    if(!obj[string[i]]) {
      obj[string[i]] = 1;
    } else {
      obj[string[i]] += 1;
    }
  }
  var count = 0;
  for(var key in obj) {
    if(obj[key] === 1) {
      return count;
    }
    count++;
  }
  return 'No unique characters';
}
console.log(indentifier(x));
