Why won’t parts of ES6 work in SoloLearn’s playground?

Question

https://code.sololearn.com/WsC4XdNWw2LT/?ref=app
So far destructuring objects and rest doesn’t work in the playground. I pasted the exact code here with destructuring an object in my browser and it worked fine. Is Solo Learn planning to fix this?

Answer 1

It's your webview (or, more specifically the JS engine Chromium's running on your mobile)

You can check your webview version here (includes a lot of feature tests):

And also check what webview versions support here (useful for other people's mobiles, or checking for bugs):

Beside what Kirk Schafer said, see here for a way to run ES6 code on device that dont support it
