Maybe it's not a proper way, but it's shorter and you got the same result

HI guys,

Maybe it's not a proper way, but it's shorter and you got the same result:

const users = [
  {name: 'Samir', age: 32},
  {name: 'Angela', age: 25},
  {name: 'Beatrice', age:56}
];

const reducedUsers = {};

users.reduce((acc, curr)=> reducedUsers[curr.name] = curr.age ,0);

console.log(reducedUsers);

I created an object, which will hold the value (acc). Each iteration I give this object a new key value pair with the current name and age value.

This is the first workshop where I wasn't able to come up with the solution to the challenge on my own. I think expecting us to figure out we need to pass an empty object as the initializer and return the object each iteration is a bit too much considering we never learned about that in the lesson.

You are correct that this is a way to do this with less code. However, I recommend that you follow along with the concepts covered in the video. It is better that you learn all the different ways to do something instead of just one way. Especially since the .reduce() method you are using will be covered in a later video.
