JavaScript Calculator feedback

Hey Guys,

Here is my JavaScript calculator project. have a look and give your feedback.

Codepen link:

The design looks really old. Would be cool if you style it a bit otherwise then that. Nicely done with JS. One day I want to be as good as you with it :3

Try to count:
2.33333 - 50 :slight_smile:

Maybe add keyboard support.
Overall good job :+1:

Some different colours would be good. All black is a little difficult to look at. And maybe increase the font on the buttons.

Good job!
