Why user.name and user[name] are not same in these conditions?

Hello there, Why these are not giving same results? I even thought user[age] is more likely reliable, but kind of feel confused here. Many thanks in advance.

const newUsersArray = users.filter(user => user.name !== 'Samir');
const newUsersArray = users.filter(user => user[name] !== 'Samir');

I believe you must use quotes around name

user["name"]

Thank you Dmitry, I thought, I was accessing user.name as a variable, as you know, when you access object properties, assuming as a variable . obj[key] , we don't need to wrap up with quotes if we access as a variable in the property. That thing confused me, Anyways, Spasibo)
