Discover the best programming language for React Native development—JavaScript or TypeScript—and how each impacts code quality and maintainability.

96 views

The best language for React Native development is JavaScript, as it is the core language of the framework. However, using TypeScript can enhance code quality by adding static type-checking, which helps catch errors early and improve maintainability. Both languages are equally supported in the React Native ecosystem.
