npm uninstall removes dependency in .json

Hello

When i use "npm uninstall express" without flags it also removes the dependency in the projects npm init (.json) file.

why is this the case? shouldnt the command "npm uninstall express --save" do this, but not the normal command?

I know that, at some point --save-prod or -P became the default behavior for "npm install". It even states it in the help "npm help install".

It seems that uninstall is also behaving as if --save or -S was the default (tested with NPM 5.6.0 and 6.1.0). The help for uninstall, "npm help uninstall", and the docs both still say that you need it.

You can use the --no-save flag to keep it from removing the dependency in package.json.
