-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();
