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.

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!
