JavaScript Calculator
A React calculator with a custom keypad, formula display, and decimal arithmetic controls.
My role: Frontend Developer
Historical demo: the keypad did not respond during review. The source code remains available.
Learning goal
Practice React components and state by handling calculator input, expressions, and results.
Behind the project
Built for freeCodeCamp with separate keypad, formula, and output components. The calculation logic handles operator changes, decimal input, and clearing the current expression. I also designed the keypad and display styling.
