cool, but your code is not beautiful
1, bad switch case
2, bad button component creation process

see my version( powered by concent)
Completely separate UI and logic!

and I found a bug when I migrate your code
when I input 3*50, the result is 750 !!!

you can fix it on my codesandbox mentioned above or yours


input 888-666, the result is 150


Hey thanx for doing the thorough testing of the app, Its really great of you for doing this. Will check the logic and update the needfull.


thank for your reply, if you have fixed it just let me know, I will copy it to my concent version.


another bug founded:

try input 5-6+1, the result is Start Calculating


Hey, this article is a head start for this concept not an assignment, so that's why it is in open space, you're free to work on it and update the code & bugs as you want. Overall I like it as it gives me space to work and improve on it, not just copy and use further. I guess you're promoting "concept" although that is nice, but put your testing in a single comment as it demotivates the readers. :)
