what is inherits fr?

This package gives JavaScript developers a simple way to set up inheritance, the mechanism where one object type borrows behavior from another. It mirrors a helper function that comes built into Node.js (a popular JavaScript runtime), but it's designed to work smoothly in web browsers too. In JavaScript, you often want one "class" of object to extend another, so a Dog can reuse everything an Animal already does. Node.js provides a function for this, but pulling that function into browser-based code normally drags along a large, heavy utility package. This project solves that by giving you the exact same function with a lightweight browser-friendly version that skips the baggage. It even includes a fallback for very old browsers. You'd use this if you're writing JavaScript that needs to run both on a server (Node.js) and in a browser, and you want inheritance to work consistently in both places without bloating your download size. For example, if you're building a UI component library that shares code between a backend and frontend, this keeps things tidy. The README recommends using it instead of the built-in Node.js version whenever your code might end up running in a browser. One thing to note: version 1.0 of this package behaved differently and isn't compatible with the current version 2.0. If you're upgrading from the old version, be aware that the way you reference a parent class changed (it now uses super_), and the new version overwrites existing prototype fields rather than preserving them. For most people starting fresh, this won't matter, but it's worth knowing if you're maintaining older code.
