Netlify is a popular tool among front-end developers for deploying and hosting applications due to its ease of use, speed, and reliability. This guide demonstrates how to build a simple React calculator app using create-react-app, integrate feature flags using Split, and deploy the app with Netlify. The tutorial highlights creating essential components, such as buttons and results, and implementing feature flags to control the rollout of new functionalities like BACKSPACE, allowing for incremental or immediate user deployment without code changes. The combination of Netlify and Split enables faster releases and quicker bug detection, offering a robust solution for front-end development. Additionally, Split provides comprehensive feature management and experimentation tools, helping teams release impactful features efficiently while maintaining high visibility and reduced risks.
