MC-148890Using data command to modify a block. There seems to be no difference between set value and merge value besides syntax.
I am editing the count of an item in a tile entity using the data command. My command looks like this:
/data modify block x y z Items[1] merge value {Count:1}
This just overwrites Items[1].Count with 1, which does exactly the same thing as:
/data modify block x y z Items[1].Count set value 1
Is this intended? If not, then this is a bug. I feel that the prior should add the count of 1 to the existing count in Items[1] while the latter should just overwrite it. This would allow creators to increment items in a reward chest for various accomplishments of a player, as well as other possible uses.

merge combines two compounds in the standard way that has been established since /entitydata (and now /data merge). Namely, it replaces all non-compound children in the destination compound with values from the source, further merges compounds, and leaves existing values in place.
[Mod] tryashtar And what is the difference to
then? The only difference I was able to find was that
does not work for single values, only compounds. But then there would be no reason for
to exist.
