Nice tutorial. I tried to write my own component that works on ie11 and had no joy.
I tried running your example under ie11:
and no joy. Any suggestions?
In my case I used dom template, not a string like you did but should be same. And I use native-shim that is made into es5. still no joy. I’d love to collaborate on ie 11 hello world. I hope you respond and this tell me that you did :-)
