  1. The JavaScript Black Hole

    A playbook for ethical engineering on the web.

    In the 25 years since JavaScript was first added to Netscape Navigator, the language has evolved from a cute little toy to an integral part of the Internet. JavaScript frameworks such as React and Angular have transformed the web, bringing us fully-fledged client side applications with functionality that could only be imagined just a decade ago. In the process, the web has become more powerful, but also much more dangerous. Malware and mass surveillance have become persistent threats, fueled by the ever-expanding amounts of user data exposed by new JavaScript features, and sucked into the black hole of omnipresent tracking networks. With real human costs, these threats have been worsened by the increasingly popular belief that "the web browser is an operating system, and everything is an app."

    This essay is written for web developers and people interested in the field. In it, I break down the problems mentioned above, demonstrate some commonly-used JavaScript practices that can expose users to harm, provide examples of actual harm being done, and ultimately propose some actionable alternatives that we, as developers, can adopt to prioritize ethical engineering and minimize harm for our users, while still building feature rich applications.
