What is deprecation?

The `deprecation` npm package is designed to help developers manage and signal deprecations within their codebase. It provides a structured way to mark certain functionalities as deprecated, issue warnings, and guide users towards alternatives or updated practices. This can be particularly useful in libraries or applications undergoing gradual upgrades or changes, ensuring backward compatibility while encouraging the adoption of new features or methods.

What are deprecation's main functionalities?

Emitting Deprecation Warnings

This feature allows developers to emit deprecation warnings with a unique ID and a message guiding users towards an alternative method or practice. The code sample demonstrates how to create a new `Deprecation` instance associated with a specific package and issue a warning about a deprecated method.

"use strict";
const Deprecation = require('deprecation');

const deprecation = new Deprecation('@mycompany/mypackage');

deprecation.warn('deprecated-method', 'The `deprecatedMethod()` is deprecated and will be removed in the next major release. Use `newMethod()` instead.');
