create-react-app running on Smart TV browser

Newer versions of React (v16+) require:

• The Map and Set data structures
• The window.requestAnimationFrame() API

According to MDN, basic Map and Set support weren't added to Chrome until version 38, and you had to use a vendor prefix to access requestAnimationFrame until Chrome 24.

Since your TV uses Chrome 23, you'll need to polyfill those APIs. The React docs suggest using core-js or babel-polyfill for this purpose.
