/*
* decaffeinate suggestions:
* DS101: Remove unnecessary use of Array.from
* DS102: Remove unnecessary code created because of implicit returns
* DS104: Avoid inline assignments
* DS207: Consider shorter variations of null checks
* DS208: Avoid top-level this
* Full docs: https://github.com/decaffeinate/decaffeinate/blob/main/docs/suggestions.md
