Say I have a folder:
./folder/
Inside it there are many files and even sub-directories.
When I execute:
mkdir -p folder
I won't see any errors even warnings. so just want to confirm, is there anything lost or changed in result of this command?

The help of mkdir says that the directories are only created when they are not present. This implies to me that when the directory exists there is nothing done.

mkdir -p would not give you an error if the directory already exists and the contents for the directory will not change.

This answer does not seem to be correct. mkdir indeed emits an error if the directory exists, unless using the -p flag.

in error, you could check for the code like thisif(err.code == 'EEXIST')this condition will get true if the directory already exists.

A portable script will rely upon POSIX, which says of mkdir's -p option:
Each dir operand that names an existing directory shall be ignored without error.
and if there are no errors reported, the -p option has done its job:
Create any missing intermediate pathname components.
