Remove single quotes from Javascript object keys

问题

我正在尝试让对象的键不被单引号包围。

let arr = [2, 3, 4, 11];
let myObj = {};
myObj[arr[2]] = true;
console.log(myObj);

上述代码输出结果为 { '4': true }

我如何去掉数字 4 周围的单引号,使其显示为 { 4: true }

英文:

I'm trying to have the key of the object not be surrounded by single quotes.

let arr= [2, 3, 4, 11];
let myObj={};
myObj[arr[2]]=true;
console.log(myObj);

The above code outputs the result { '4': true }

How do I remove the single quotes around 4 and have it display as { 4: true }

你可以这样做:

const arr = [2, 3, 4, 11];
const myObj = {};
myObj[arr[2]] = true;
const str = JSON.stringify(myObj);
console.log(str.replace(/[",']/g, ''));
英文:

You can do it like so:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const arr = [2, 3, 4, 11];
const myObj = {};
myObj[arr[2]] = true;
const str = JSON.stringify(myObj);
console.log(str.replace(/[&quot;,&#39;]/g, &#39;&#39;));

<!-- end snippet -->
