How mahmudur26/emo-cal works
Emo Cal is a small web calculator: a visitor opens the calculator page, enters two integers and an operator, then submits the calculation and receives operation details as JSON. The documented routes and response shape establish the main flow. The frontend JavaScript and calculation implementation were not sampled, so their internal wiring is not expanded here.
Main entry points: Calculator.php Calculator controller · index.php HTTP entry · web.php Web routes · calculator.blade.php Calculator page
