From Discord: Modification of ReadonlyArray.groupBy Signature

[effect-bot]

Summary

In the above conversation, there was a suggestion to modify the signature of the ReadonlyArray.groupBy function in the Effect-TS ecosystem. The initial suggestion was to change the type parameter from string to a more generic K extends string. This would allow for more flexibility in the keys used for grouping.

Later, there was a suggestion to further refine the type parameter to K extends string | symbol, which would also allow for grouping by symbols.

Additionally, it was mentioned that there is an upcoming release of Effect-TS that includes a new utility type called ReadonlyRecord.NonLiteralKey<K>, which can be used to ensure that the keys used for grouping are not literal types.

The key takeaways from this conversation are:

1. There is a suggestion to modify the signature of ReadonlyArray.groupBy to allow for more flexible key types.
2. The suggestion includes using a generic type parameter K extends string | symbol to allow for grouping by both string and symbol keys.
3. There is an upcoming release of Effect-TS that includes a new utility type ReadonlyRecord.NonLiteralKey<K>, which can be used to ensure non-literal key types are used for grouping.
