Support for groupBy

[ehdrms785]

Hello, @raon0211

It would be great if groupBy could be added to es-toolkit.

Could I try implementing this ?

Ex ) https://lodash.com/docs/4.17.15#groupBy

We actually already have groupBy in our library. Is this insufficient?

Apologies, it was my mistake. I’m not sure why the groupBy method didn’t catch my eye when I was looking for it. I thought there might be some method for performance improvement, So I tried using a pure object.

Although I obtained some meaningful results, using a pure object—thus not utilizing the prototype—seems like a risky approach.

I’ll definitely participate again as a contributor if I have the opportunity in the future!

Thanks for giving attention to our project! Although the performance is a little lower than original lodash, our function has significantly slower bundle size. In addition, we will optimize our function in the future :)
