Answer 1

As far as I know Sololearn has done pretty good job on playground ES6 support. I have couple of ES6 codes which runs with no problems, perhaps you could check my codes to clear your doubts.

Answer 2

Maybe You didn't make your code into strict mode?
Or you use old android?

Answer 3

on my py shell too smtimes this happens and then I restart the console..

Answer 4

Sololearn background uses phone browser to run the code. Code run on new phone should support most ES6 codes.

Answer 5

@BenBright I have used simple example like let x = 5; console.log(x); but it says error in line 1 where I wrote let even the color wasn't changing up when was writing let

Answer 6

As calvin stated,it uses the phone's WebKit system to interpret JavaScript.Your phone maybe have an older WebKit which doesn't support ES6 yet.
