具有 getter 和 setter 的 JavaScript 类会导致 RangeError：超出最大调用堆栈大小

我目前正在尝试 ECMA6 课程。 我当前的课程如下所示

class Player {
  constructor(id) {
    this.id = id;
    this.cash = 350;
  }

  get cash() {
    return this.cash;
  }

  set cash(value) { // line 19
    this.cash = value; // line 20
  }
};

当我现在通过调用创建一个新对象时let playerObject = new Player(1);我收到以下错误

...\node_modules\mysql\lib\protocol\Parser.js:82
        throw err;
              ^
RangeError: Maximum call stack size exceeded
    at Player.cash (player.js:19:11)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
    at Player.cash (player.js:20:15)
Press enter to exit

这和mysql库有什么关系呢？为什么同一行多次出现错误？我只调用一次。

您的“现金”设置器调用“现金”设置器，“现金”设置器调用“现金”设置器，后者调用“现金”设置器......

在设置器内通过属性设置器自己的名称访问属性设置器会创建无限递归函数调用。
