mongod command for using mongodb-community version in Macos Mojave gives error

Question

I am using macos Mojave 10.14.5 on a Macbook Air 2017. I have installed mongodb-community version using terminal by running the commands,

brew tap mongodb/brew
brew install mongodb-community

after that I also made the default folder using,

sudo mkdir -p /data/db

and I changed the ownership as,

sudo chown -Rv dhruvbansal /data/db

Then I ran the command mongod in the terminal but it is not starting the mongo-daemon shell. The screenshot is attached here.
