How to merge all objects in an array

[khanh_tran]

I got an array named “group” includes object items as the below picture

How can I merge all object items to one object? My expected result as the below picture. But, imagine that the number of item is unknown. It can be 3,4,5 , … (n).

Thank you!

Just use the following expression, this should do the job:

{}.extend(...$group)

This will simply put all objects from the array into a single object and it will overwrite duplicate keys.

{}.extend(...$group)

Thank you. But my problem here is “I don’t know how many item in $group array”. I cannot type {}.extend($group[0],$group[1],$group[n…]) (T_T)

That won’t be a problem here, because I’m using destructuring assignment ( the three dots ) before the $group array ...$group, this will always work for every $group array regardless of the array size, you don’t have to get each index from the $group array, just use ...$group, this will destructure the array and will be the same as writing $group[0]... $group[n] multiple times.

{}.extend(…$group)

Woah. That’s great. I didn’t know that. You’re my hero. hahaha. Here is my result. I worked.
