re: The shortest way to conditional insert properties into an object literal VIEW POST

re: I've already expressed mine opinion here around, and to be technically precise the code is easily testable as any if construct. Thanks for sharing ...

I do find the article helpful but to be honest with you, it was the first time I saw something like this.

I guess someone that is more experienced with the spread operator and augmenting objects in this way might have seen it more than me.

As you said, it is most probably a matter of opinion as a lot of things in javascript are those days, for example, I find something like this pretty hard to read:

let adder = (x) => (y, z) => x + y + z;

compared to the old-style alternative but there are people who love it.

So thank you again for going deep in your explanation :)
