Yesterday I found I needed to de-duplicate an array of objects. The problem is, I needed to compare the objects in their entirety, not just by an individual key. I was quite surprised to find something was not already written up, and shared, on the interwebs.
Maybe it’s rare that one needs to get a unique array of objects by comparing the entire object. Or maybe it’s not very performant so folks don’t bother. Either way, here’s what I came up with. I hope you find it helpful. If you come up with a better method, please do let me know.
