Didn't see anything like this. I find it is useful.

Looks good .. Thanks!
I will add a documentation for it.

Added to version #v0.5.2 with small changes in behaviour, it will now return an object that it's property will be the grouped by property.

Take a look at the readme file for more documentation, if you would like to use it in an ngFor you could add an additional keys pipe to loop over it, since Angular2 doesn't support loop over objects.

Looks good. Would it make sense to have another pipe like lodash’s toPairs? https://github.com/lodash/lodash/blob/4.17.2/lodash.js#L1011 <https://github.com/lodash/lodash/blob/4.17.2/lodash.js#L1011>

Might be a good idea yeah.
I'll try to find a time for it.
