Hi! I think you should have started with the basic nature of JavaScript.

Like, an introduction of it's async nature, or maybe template literals in your String section. It would have been more like a Javascript introduction that way.

It would have also been better for beginners if you had introduced the var keyword and arrow functions since only Javascript have those features.

I hope you would take these suggestions in a constructive way. I too post articles about Javascript on Medium so you can anytime ask for help if you like😊
