@ansh7432 dependencies and devDependencies are two different and important parts of the package.json file, so we cannot just remove something from dependencies and put it into devDependencies.

dependencies are what gets installed on the user's computer and devDependencies (along with dependencies) are what gets installed on the developer's computer who is working on the particular package.

Also, nightwatch shouldn't be a part of devDependencies.
