Changing the native Date object in the accepted answer is bad practice;在接受的答案中更改本机Date对象是不好的做法； don't do that ( https://stackoverflow.com/a/8859896/3929494 )不要这样做（ https://stackoverflow.com/a/8859896/3929494 ）
You should use moment.js to give you a consistent environment for handling dates in JavaScript between node.js and all browsers - see it as an abstraction layer.您应该使用 moment.js 为您提供一个一致的环境，用于在 node.js 和所有浏览器之间处理 JavaScript 中的日期 - 将其视为一个抽象层。 http://momentjs.com/ - it's quite easy to use. http://momentjs.com/ - 它很容易使用。

The browser output is showing the date in the current time zone, node.js is showing the date GMT / Zulu time zone.浏览器输出显示当前时区的日期，node.js 显示日期 GMT / Zulu 时区。
(Edit: Code added). （编辑：添加了代码）。 Something like this像这样的东西
var offset = (new Date().getTimezoneOffset() / 60) * -1;
var d = new Date();
var tmpDate = new Date(d.getTime()+offset);
var y = tmpDate.getFullYear();
var m = tmpDate.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);
console.log(tmpDate.toString());
console.log(firstDay.toString());
console.log(lastDay.toString());

Create a new file dates.js and add the following code.创建一个新文件dates.js并添加以下代码。 To execute this code run the command node dates.js from your terminal.要执行此代码，请从终端运行命令节点dates.js 。 You can use this function to get first and last days dates in a given month.您可以使用此函数获取给定月份的第一天和最后一天的日期。 I tested this on node 12我在节点 12上测试了这个
const getDays = () => {
const date = new Date();
const year = date.getFullYear();
let month = date.getMonth() + 1;
let f = new Date(year, month, 1).getDate();
let l = new Date(year, month, 0).getDate();
f = f < 10 ? '0'+f : f;
l = l < 10 ? '0'+l : l;
month = month < 10 ? '0'+month : month;
const firstDay = new Date(`${year}-${month}-${f}`);
const lastDay = new Date(`${year}-${month}-${l}`);
console.log({
"firstDay": firstDay,
"lastDay": lastDay
});
};
getDays();

Look at the code看代码
<html>
<head>
<title>Please Rate if it helps</title>
<script>
Date.prototype.getMonthStartEnd = function (start) {
var StartDate = new Date(this.getFullYear(), this.getMonth(), 1);
var EndDate = new Date(this.getFullYear(), this.getMonth() + 1, 0);
return [StartDate, EndDate];
}
window.onload = function () {
document.write(new Date().getMonthStartEnd());
}
</script>
