process 进程

源代码: lib/process.js

process 对象提供有关当前 Node.js 进程的信息并对其进行控制。 作为全局变量，它始终可用于 Node.js 应用程序，而无需使用 require()。 也可以使用 require() 显式地访问它：

const process = require('process');

Source Code: lib/process.js

The process object is a global that provides information about, and control over, the current Node.js process. As a global, it is always available to Node.js applications without using require(). It can also be explicitly accessed using require():

const process = require('process');
