Last release:

This package provides an ES3-compatible polyfill for `String.prototype.includes` (previously `String.prototype.contains`) for use in older JavaScript environments. It’s designed to be robust and optimized, and it implements the es-shim API interface so you can add `includes` behavior where it is missing.
