Answer 1

Please see here . It shows up with a particular Chrome Canary version, and it seems due to es6-shim. It has been reported to have been fixed in es6-shim v0.34 . Or you can switch to core-js shim, as mentioned here .

But if you're using some library (like Ionic) that depends on a particular es6-shim version, I guess you'd wait for library update.
