/**
|
* The `console` module provides a simple debugging console that is similar to the
|
* JavaScript console mechanism provided by web browsers.
|
*
|
* The module exports two specific components:
|
*
|
* * A `Console` class with methods such as `console.log()`, `console.error()` and`console.warn()` that can be used to write to any Node.js stream.
|
* * A global `console` instance configured to write to `process.stdout` and `process.stderr`. The global `console` can be used without calling`require('console')`.
|
*
|
* _**Warning**_: The global console object's methods are neither consistently
|
* synchronous like the browser APIs they resemble, nor are they consistently
|
* asynchronous like all other Node.js streams. See the `note on process I/O` for
|
* more information.
|
*
|
* Example using the global `console`:
|
*
|
* ```js
|
* console.log('hello world');
|
* // Prints: hello world, to stdout
|
* console.log('hello %s', 'world');
|
* // Prints: hello world, to stdout
|
* console.error(new Error('Whoops, something bad happened'));
|
* // Prints error message and stack trace to stderr:
|
* // Error: Whoops, something bad happened
|
* // at [eval]:5:15
|
* // at Script.runInThisContext (node:vm:132:18)
|
* // at Object.runInThisContext (node:vm:309:38)
|
* // at node:internal/process/execution:77:19
|
* // at [eval]-wrapper:6:22
|
* // at evalScript (node:internal/process/execution:76:60)
|
* // at node:internal/main/eval_string:23:3
|
*
|
* const name = 'Will Robinson';
|
* console.warn(`Danger ${name}! Danger!`);
|
* // Prints: Danger Will Robinson! Danger!, to stderr
|
* ```
|
*
|
* Example using the `Console` class:
|
*
|
* ```js
|
* const out = getStreamSomehow();
|
* const err = getStreamSomehow();
|
* const myConsole = new console.Console(out, err);
|
*
|
* myConsole.log('hello world');
|
* // Prints: hello world, to out
|
* myConsole.log('hello %s', 'world');
|
* // Prints: hello world, to out
|
* myConsole.error(new Error('Whoops, something bad happened'));
|
* // Prints: [Error: Whoops, something bad happened], to err
|
*
|
* const name = 'Will Robinson';
|
* myConsole.warn(`Danger ${name}! Danger!`);
|
* // Prints: Danger Will Robinson! Danger!, to err
|
* ```
