Creating a package.json file in JavaScript

You can create a package.json file with all the necessary settings using a terminal. To do this, you need to run the following command:

npm init

After running the command, a terminal will ask you for the parameter values, and after that it will create the package.json file.

If you don't want to answer questions, then using the -y flag you can force the terminal to answer "yes" to all system questions:

npm init -y

Using a terminal, open a folder in it and create a package.json file in this folder.
