如何用node执行js代码

以前没怎么写过前端代码，一直以为，写前端代码需要在浏览器里面执行，打开控制台，然后debug之类的。
首先写一段js的代码

// 类
class Animal{
    constructor(name) {
        this.name = name
    }
    run() {
        return `${this.name} is running`
    }
}
const snake = new Animal('lily')
console.log(snake.run())


class Dog extends Animal{
    bark(){
        return `${this.name} is barking`
    }
}

const xiaobao = new Dog('xiaobao')
console.log(xiaobao.run())
console.log(xiaobao.bark())

进入cmd窗口,执行命令node class.js

c>node class.js
lily is running
xiaobao is running
xiaobao is barking
