Hash and Equality

[xaviergonz]

To properly create a dictionary/set etc two things are needed in .net

getHashcode method to get the hash of the object to know in which bucket it must be placed
an equals method to know which object to pick up on the bucket if the hash collides

I don't see any implementation of those in the collections, how are they handled by this library?

Hi, the library uses comparers for this. You can let the library use the ones provided by me (tested with all native JS types) or provide your own.

There are multiple overloads using them: https://github.com/isc30/linq-collections/blob/master/src/Enumerables.ts#L106

In case you need to use comparers on a method that doesn't accept them, I will gladly accept a PR (this should be 4-5 lines change at most) or you can request it and I'll add it on my spare time.

Thanks for the feedback 😄
