Thanks again for looking at my problem.

I understood that it eslint is not needed to resume the tutorial and I did what showed with your package.json.

I didn’t know about npx as I’m supposed to learn the essentials and having the minimal working steps to reach some knowledge !

What troubles me the most is that eslint on the the index.js file ends up saying that require() is not defined !

Having followed other node.js and javascript tutorial, I would have use “import”/“export” to include other .js file in ES6. But I’ve noticed that node would not recognize that syntax and I should use require().

Now, the eslint package does not recognize require, it is quite shocking !
It is already confusing elsewhere, I did not expect more confusing here at MDN !

Thanks again Chris, I’m still following the tutorial.
