Array.prototype.uniqBy

This looks pretty reasonable, And I don’t have any issues with either. though I don’t think uniqby should encompass both of these. Instead we would have to also do something like uniqWith. The example for the uniqWith behavior was hard to follow because it’s the same as uniqBy but it’s usecase is different, I think the load should documentation has a good example for anyone trying to understand: https://lodash.com/docs#uniqWith
