Hi My name's Jordan, and I've gradually mutated over the last decade into being super obsessed with open source, backwards compatibility, and finding ways to balance what I feel are ethical obligations to all users of projects I interact with, with the very real problem of time management, burnout, and work/life balance.

I've been a part of TC39 (the committee that writes the specification for JavaScript) since 2014, and I was an editor of the specification from 2018-2021. I've been heavily involved in the node community for as many years, and I've gradually created (but mostly inherited or been gifted) a decent number of open source projects. I persist in trying to maintain them all with maximal back compat, the strictest adherence to semver, and the greatest respect for users.

Projects I Maintain

qs nvm.sh resolve tape
airbnb javascript styleguide/eslint configs prop-types compat-table es-abstract
enzyme organization enzyme
es-shims organization es5-shim es6-shim object.assign
inspect-js organization object-inspect deep-equal
jsx-eslint organization eslint-plugin-react eslint-plugin-jsx-a11y
import-js organization eslint-plugin-import

… and many more on npm

Standards/Communities I Contribute To

this includes participation in working groups, committees, meetings, general issue triage, etc

How Sponsorship Helps

Although open source is a huge part of my life, it's not the most important part - I have a spouse, kids, and a dog; bills to pay; and I also try to give back to the wider community.

Sponsorship helps fund domains, travel, but also other sponsorships

    While attempting to explain JavaScript's `reduce` method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Error subclasses: how are they checked?

(from #263) Checking the [[ErrorData]] slot ensures it's an Error or an Error subclass. However, when someone matches against, say, TypeError, we o…
