Coding Challenge

Create a bot calculator using Typescript, socket.io and mongoDB.

Requirements

1. I can open the app in a browser that contains a command input
2. I can chat with the bot using only 2 possible command types
3. Operation command: 1 + 1 or 5 * 3, 1526 - 1452 + 5623 * 2, ...
   • operators: +, -, *, /
   • number: integer, floating point
4. History command: history to display latest 10 calculations used
   • History can be dropped on app restart
5. The code can be accessed through your github/gitlab account, please send us a link when you’re done.
6. Please use multiple commits and descriptive commit description
7. Implement unit testing
8. Split it up into a frontend and a backend (use the MERN stack)
9. Using typescript will be a bonus.
10. Please avoid using the eval-cmd of the JS math library
11. The more effort you put into it (e.g. design wise, documentation wise) the better the rating will be.
