What is localStorage?

LocalStorage is the data storage type of web storage. This allows the Javascript sites and apps to store and access the data without any expiration date. The data will always and it will not expire even after the browser close.

Short solution

To store the array in localStorage, we are going to use the setItem() method to add the data in localStorage. setItem() method accepts the two parameters that are key and value. And using the JSON.stringify() method will convert the array into a string and store it in localstorage. Let’s see the code syntax:

let Obj = ['Sunday','Monday','Tuesday','Friday'];

//store the name data in localStorage
localStorage.setItem('Obj',JSON.stringify(Obj));    //localStorage.setItem(key,value);

// get data from localStorage
let objt = JSON.parse(localStorage.getItem('Obj'));

console.log(objt);  // ['Sunday','Monday','Tuesday','Friday']

Short Example

Let’s understand with an example. First, we are going to store the array in localStorage.


    <h1>Data from localStorage</h1>
      <p v-if="objData">website : {{ objData[1] }}</p>
      <button @click="addData">Add Data</button>
export default {
  name: "FirstComponent",
  data() {
    return {
      obj: ["Sunday", "Monday", "Tuesday", "Friday"],
      objData: null,
  methods: {
    addData() {
      localStorage.setItem("Obj", JSON.stringify(this.obj));
      this.objData = JSON.parse(localStorage.getItem("Obj"));

For now, let’s check the output.
