EN

    var data = {
       name:'john',
       age:20
    }

    localStorage.setItem('data',JSON.stringify(data));

    // To get data back

    var data = JSON.parse(localStorage.getItem('data'));

   // Editing data

   data.name = 'mark';

  // Saving Back

  localStorage.setItem('data',JSON.stringify(data));

localStorage.hello   = "Hello World";
localStorage.hello   = "Hello World. Part 2.";
localStorage.getItem("hello") // "Hello World. Part 2.";

localStorage.removeItem("hello");
