What's the end goal? To reduce the size of a serialized JSON? Maybe a stringify that removes nulls and undefineds would be more suited if so. If not, I can't see what your end goal could be (can't be for iteration over an object, since that would also require a defined check to handle both cases, so no gain)?
Yeah, it was wrong, I'm currently using like
let ret = { ... ( couldBeNull ? {couldBeNull} : {} ) }Yours is better and the usual idiom a bit hard to understand.
What I'm proposing is something like this
let ret = { couldBeNull? }or if you want a different name for the property
let ret = { bar ?: couldBeNull }It is not like there is no way to do this, there are plenty. But this way could make code a bit easier to read.
