People still use Underscore?

I am aware of underscore as a nice blob of simple utility functions. I'm not aware of what you would replace it with?

lodash is basically an underscore replacement. https://lodash.com/

For a second there I thought we might get a thread that mentions Underscore without Lodash being plugged.

Oh well, maybe next time.

While the map() should be written in pure JS standard lib, the _.groupBy() is reasonable.
