描述

¥Description

禁止分配给原生对象和只读全局变量。

¥Disallow assignments to native objects and read-only global variables.

JavaScript 的环境包含许多内置的全局变量，例如浏览器中的 window 和 Node.js 中的 process。为这些全局变量赋值可能会出现问题，因为它可能会覆盖基本功能。

¥JavaScript’s environments contain numerous built-in global variables, such as window in browsers and process in Node.js. Assigning values to these global variables can be problematic as it can override essential functionality.
