Why do we need Redux If we can use JavaScript LocalStorage?

As a JS Developer, Today I was learning JavaScript and found a thing called LocalStorage where we can store data in the variables just like PHP Sessions and then call it wherever we want. Then what I felt like is LocalStorage is the same as Redux. I might be missing something which can make Redux different from Js LocalStorage. So that's why a question just arose in my mind that Why do we need Redux. Can we seriously use LocalStorage instead of Redux?
