I have zero knowledge about programming, I gave a try asking Chat GPT to program a calculator app using CSS, HTML and JS. And damn, it created it!!!

Prompt I used: 
"Generate a code for a calculator, it should be interactive, the look should be dark and aesthetic. It should be a web-based app and use only HTML, CSS, and JavaScript. It should also be responsive and placed in the centre of the screen. Please provide all the code in one file and give steps to run it."

PS: I learned how to give this prompt from this video. 

(lol, I know calculator might be as easy as asking the code to generate "hello world" but this is fun for a nontech guy XD)
