How to Use the New JS Object GroupBy Method

very helpful details
thanks for your great videos

Congratulations on 100K subscribers,
and thanks a lot for sharing your knowledge and expertise

Great video, Thank you

behind the scene
movies.reduce((groupBY, item) => {
if(!groupBY[item.series]) groupBY[item.series] = [];
groupBY[item.series].push(item)
return groupBY
}, {})


I don't understand the purpose of adding things without some benefit...
nothing less code is written...

who does not understand reduce, will not understand this either

Finally Steve is back!

why is this in object and not in array?.

Lipstick on a pig (map method)? But it looks useful, thanks Steve.

Thank you professor for the great video

great ! can we also sort this based on no. of items in series instead of random order (length of keys : []) ?

I always enjoy your videos, cheers on those 100K!

Hello Sir, can you please make videos on node js background processes, how the cores come into play?

I always enjoy your videos, something new I learned today, thanks Steve

Is there a way of using this function to do a 2-level nested grouped Map/Object, if one were to provide a pair of keys, e.g. { key, sub-key }

Welcome back! Just noticed your new videos. Yes!

100k! It was a long journey but very well deserved. Congratulations!

It would be nice to add performance comparison section to the video.
