userObject is not defined

I've copied and paste the reduce method in the video.

const userObject= users.reduce((userObject, user) =>{ usersObject[user.name]=user.age; return usersObject; },{}); But my browser end up with the error "userObject is not defined".

It happens even if I change the name to something else.

Hi Emil!

Maybe it's because:

You are using usersObject instead of userObject. Try this code out:

const userObject = users.reduce((userObject, user) => {
  userObject[user.name] = user.age;
  return userObject;
}, {});

I hope it works!
