* 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__
|
|
* DS104: Avoid inline assignments
|
|
* DS204: Change includes calls to have a more natural evaluation order
|
|
* DS207: Consider shorter variations of null checks
