- * decaffeinate suggestions:
- * DS101: Remove unnecessary use of Array.from
- * DS102: Remove unnecessary code created because of implicit returns
- * DS104: Avoid inline assignments
- * DS202: Simplify dynamic range loops
- * DS206: Consider reworking classes to avoid initClass
- * DS207: Consider shorter variations of null checks
- * DS209: Avoid top-level return
