node.js - Node.js REPL 中的 'clearBufferedCommand() 方法有何作用

Question

Node.js 中的“clearBufferedCommand()”方法有什么用？

此代码来自 Node.js 规范，但我看不到此方法的任何用途。

const repl = require('repl');const replServer = repl.start({ prompt: '> ' });replServer.defineCommand('sayhello', {    help: 'Say hello',    action(name) {        this.clearBufferedCommand();        console.log(`Hello, ${name}!`);        this.displayPrompt();    }});

来自docs :

The replServer.clearBufferedCommand() method clears any command that has been buffered but not yet executed. This method is primarily intended to be called from within the action function for commands registered using the replServer.defineCommand() method.
