* decaffeinate suggestions:
|
|
* DS101: Remove unnecessary use of Array.from
|
|
* DS102: Remove unnecessary code created because of implicit returns
|
|
* DS202: Simplify dynamic range loops
|
|
* DS205: Consider reworking code to avoid use of IIFEs
|
|
* DS207: Consider shorter variations of null checks
