What is React Native?

Welcome to React Native for Beginners! Every app you use runs on either iOS or Android, two completely separate ecosystems with their own languages, tools, and release processes. In this lesson, we break down how mobile apps are made, why maintaining two codebases is painful, and how React Native solves that problem by letting you build for both platforms with one shared codebase.

What You'll Learn

• How iOS and Android development work and why building two separate apps is expensive
• The story behind React Native, how Meta created it to solve their own two-codebase problem
• What you'll build in this crash course: a Pokedex app covering API calls, styling, and navigation
