I have updated chrome and even my Android version is 5.1. But still the code playground doesn't support ES6. What should I do?

Answer 1

See whether this article can help you, and visit the second link (choose PlayStore when asked for it) to see if there's update available.

Answer 2

The Playground uses the system web view, an inbuilt browser of Android, to display web content. Since Android 5 was released before ES6 was published it's possible that your web view don't support ES6 although it is usually updated via Playstore. If you want a newer OS version you could have a look at the lineageOS website whether your device is supported: https://lineageos.org. lineageOS is a Android version that supports even devices that usually would receive updates from the manufacturer. It's also what runs on my Smartphone. And as a bonus you can easily get rid of all the bloat Google installs on top of Android.
