This is a polyfill that adds the ES6 `String.prototype.includes` method to environments that don't support it natively, allowing developers to use this modern string method in older JavaScript engines. It's designed for developers who need to write ES6-compatible code but must support older browsers or environments that lack this feature.

Support the dependencies of mathiasbynens/string.prototype.includes
Robustly `.call.bind()` a function
Define multiple non-enumerable properties at once. Uses `Object.defineProperty` when available; falls back to standard assignment in older engines.
ECMAScript spec abstract operations.
Loosely test a package's compliance with the es-shim API
My shareable eslint config
Does this JS environment support the `name` property on functions?
Yet another JS code coverage tool that computes statement, line, function and branch coverage with module loader hooks to transparently add coverage when running tests. Supports all JS coverage use cases including unit tests, server side functional tests and browser tests. Built for scale
Given an object and a property, replaces a property descriptor (or deletes it), and returns a thunk to restore it.
