npm install -D vs npm install --save-dev (will add in package.json, where?) any example? @types, linters , tests etc, not for production

npm uninstall (manually from package.json)

# Steps to follow

First create an index.js file in a new folder

Add simple `console.log('hello world')` in it

Run the file using `node index.js`

You should see hello world on console

Now, run the file using `./index.js`

`./` is used to run executable files, like you run .exe files on windows

But, you may get permission denied error. Because every file and folder have one of three permissions. Either Read, Write, Execute

run `ls -la`

So, by default `.js` files are not executable files

add permissions using chmod +x index.js
create pcke json, add bin nd commng
add shebang

npm link

npm login

npm publish

unlink
