- * decaffeinate suggestions:
- * DS101: Remove unnecessary use of Array.from
- * DS102: Remove unnecessary code created because of implicit returns
- * DS103: Rewrite code to no longer use __guard__, or convert again using --optional-chaining
- * DS104: Avoid inline assignments
- * DS206: Consider reworking classes to avoid initClass
- * DS207: Consider shorter variations of null checks
