Warning, this module has malicious behaviour
This is a demonstration module used in my blog post on malicious node modules. If you import this module, it will return a function which multiplies a number by two. Additionally, it will attempt to hijack express in a manner that adds a malicious payload to every request which intercepts stripe's client side library. See the blog post for more details.
This code is explicitly designed to not be very copy-and-paste portable, and will likely fail when imported into a project that doesn't behave exactly the same as the companion repository for this project.
