DISABLE_THIRD_PARTY_CHECK=new npm module causes package-lock change We can get rid of a custom script and use ESLint for these rules. Additionally this means editors will highlight the issue in the editor.

/**
|
|
* Splits a list into sub-lists stored in an object, based on the result of
|
|
* calling a String-returning function on each element, and grouping the
|
|
* results according to values returned.
|
|
*
|
|
* Dispatches to the `groupBy` method of the second argument, if present.
|
|
*
|
|
* Acts as a transducer if a transformer is given in list position.
