Use the "forEach" method to add properties to "friendsObj"? Use index as key and name as the value of property.friendsObj will have with 3 properties

Here is my current code

 var friendsObj = {};

var friends = ['John', 'Peter', 'Mary'];

 friends.forEach(function(name, index) {
  // implement your code below
    console.log('Index '+ index + ' equals ' + name ) ;
  });

console.log(friendsObj[0] === 'John');
// -> true
console.log(friendsObj[1] === 'Peter');
// -> true
console.log(friendsObj[2] === 'Mary');
// -> true

The results are this

Index 0 equals John Index 1 equals Peter Index 2 equals Mary false false false Randomized with seed 51872 Started F

Says that friendsObj should have "John", "Peter", and "Mary" as properties. I don't understand how it is not connecting back to friendsObj? Open to suggestions, thank you so much!

You need to set the property in the object for each index to be the element value.

var friendsObj = {};
var friends = ['John', 'Peter', 'Mary'];
friends.forEach(function(name, index) {
  friendsObj[index] = name;
});
console.log(friendsObj);
console.log(friendsObj[0] === 'John');
console.log(friendsObj[1] === 'Peter');
console.log(friendsObj[2] === 'Mary');

This can be written more concisely by directly converting the array into a regular object with spread syntax.

let friends = ['John', 'Peter', 'Mary'];
let friendsObj = {...friends};
console.log(friendsObj);
