UraL Probably you have an android version less than 5 (like me) where default web engine dont support ES6 (eg first standard than define let keyword). For make it work without change your device is run the code on web engine than support ES6..... Try to run the code on newest version of Chrome, Firefox for android, Kiwi than dont use default web engine but a custom and updated one
