Can I create a console application using JavaScript only?

Question

Can I create a console app using only JavaScript, or do I need to make one with UI using HTML & CSS too?

Answer 1

You can make it inside console, but by default to run javascript you need to connect it to html and open with browser, then open developer tools and check console.

But now with node.js you can run js code outside of browser so it is posible, but if you never do this, you need little bit of setup (installing node.js), you have tutorials on internet, to setup everything you need.
