-LocalStorage, Session, Cookies

1. Three type of storages have own Life time duration, memory sizes and control points. 2.Additionally if we should save Object, Array or such kind of Data bases, Firstly we change them to string via JSON KEYS like this.

const person={
    name:"John",
    age:21,
    job:"Programmer",
    hobby:['sleeping']

};

LocalStorage.setItem('person', JSON.stringify('person'))

                       LocalStorage

LocalStorage is controled only by client-side, limit of memory is 5/10mb it depends on the browser,it only supports the type of string data base and it could edit by users.

LocalStorage used with these keys:

1. setItem -> Add

LocalStorage.setItem('name', 'John');

1. getItem -> Value

let person=LocalStorage.getItem('name');
console.log(person);

1. removeItem -> remove

LocalStorage.removeItem('person');

1. clear -> clear the full storage

LocalStorage.clear();

                       Cookies

Cookies more used for Safty and it only save a few dates arround 4kb, if we want to delete it we can but other case it is not deleted. Cookies controlled by both side it client-side and server-side and it accept requests also supports string and editable.

                       Session

Sessin can save 5mb memory size , it removed when we close the tab and it also support string and controlled by client-side.
