Why I Bundled My Small JavaScript Calculators Into One Practical Kit

Over the last few weeks, I built a few small calculators as side projects: A BMI calculator An EMI calculator A simple interest calculator Each one was built using plain HTML, CSS, and vanilla JavaScript. After finishing them, I realized something — They actually make more sense together than separately. The original goal wasn’t to create products.
