Building BMI Calculator Using ReactJS

Building BMI Calculator Using ReactJS

The BMI Calculator is a beginner-friendly React project that lets users input their weight and height to calculate their Body Mass Index. It provides both the BMI value and a health status category (like Normal, Overweight, or Obese). The app uses functional components, useState, and basic event handling. It's fully styled with CSS and deployed live on Netlify for public access.
