Question
I'm trying to run a React application on Tizen TV OS 2.4 (Samsung TV PM32F) but encountering issues with JavaScript compatibility. Specifically, I'm using the create-react-app starter template and building with Tizen IDE (2.4.0_Rev8), but getting the error: "static/js/main.061688ca.js (1) :ReferenceError: Can't find variable: Set".
The same .wgt file works fine in the SDK simulator, but fails on the actual TV. I've tried multiple React and Webpack starters without success. How can I properly build JavaScript assets for Tizen TV compatibility and streamline the development process?
Answer
Problem Understanding
The core issue stems from JavaScript compatibility problems between modern React applications and the older JavaScript engine in Tizen TV OS 2.4. The error indicates missing ES6 features (like Set) that aren't supported in this version.

Additional Tips
- For Tizen TV-specific development, refer to Samsung's developer resources at https://developer.samsung.com/tizen
- When debugging, ensure you're using the correct Web Inspector version that matches your TV's OS
- Test frequently on actual hardware as simulator behavior may differ
