访问 Node.js 核心模块

默认的求值器会在使用时自动将 Node.js 核心模块加载到 REPL 环境中。 例如，除非另外声明为全局变量或作用域变量，否则输入 fs 将按需评估为 global.fs = require('fs')。

> fs.createReadStream('./some/file');

The default evaluator will automatically load Node.js core modules into the REPL environment when used. For instance, unless otherwise declared as a global or scoped variable, the input fs will be evaluated on-demand as global.fs = require('fs').

> fs.createReadStream('./some/file');
