I am trying to loops through these array's but am getting this error "Legacy octal literals are not allowed in strict mode"

const myList =[
    {
        id: 01,
        title: 'FrontEnd Engineer',
        name : 'Sheshathri',
        describtion: "simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book"
    },

        title: 'QA Engineer',
        name : 'Jobin',
        describtion: "It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.

In App.js

import myList from './ContentList';

const listItem = myList.map(list => <Content key= {list.id} title = {list.title} name = {list.name} describtion = {list.describtion} />);

• strict mode by default throws error for legacy methods/code, you should avoid legacy code – Amruth Commented Jul 31, 2021 at 16:47

It refers to yours ids:

id: 01,
title: 'FrontEnd Engineer',

Replace with

id: 1,
title: 'FrontEnd Engineer',

Octal literals are numerals that begin with a leading zero, such as:

var num = 071; // 57

The leading zero to identify an octal literal has been a source of confusion and error in JavaScript. ECMAScript 5 deprecates the use of octal numeric literals in JavaScript and octal literals cause syntax errors in strict mode.
