ReactJS 中的 "Legacy octal literals are not allowed in strict mode" 是什么意思？

Question

我正在尝试循环遍历这些数组，但收到此错误“严格模式下不允许使用传统八进制文字”

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"
    },
    {
        id: 02,
        title: 'QA Engineer',
        name : 'Jobin',
        describtion: "It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum."
    }
  ]
  
  export default myList;

在App.js

import myList from './ContentList';

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

Answer 1

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

它指的是你的id：

id: 01,
title: 'FrontEnd Engineer',

替换为

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.
