- Could you show the code of NewsFeed? – Knerd Commented Feb 27, 2015 at 8:20

Was the
NewsFeedclass loaded successfully before it was used in your code? The class needs to be loaded before it is used. You should be able to confirm using Network tab do rev tools. Then, set a breakpoint if that works. Is everything in the right sequence? – WiredPrairie Commented Feb 27, 2015 at 11:49 - It seems than newsfeed.js has an error, it fails with "SyntaxError: missing ; after for-loop initializer" when I run it through JSLint, it show it for the line: for(tag of tagArray){ - IE plained about missing ; , so at least I found the reason. But I can't figure out how to fix it. I will try different looping algorithm. – Kokesh Commented Feb 27, 2015 at 12:05
- Are you using a transpiler? – helpermethod Commented Feb 27, 2015 at 12:37

Reset to default 2Solved it. IE11 didn't like this part of newsfeed.js:
for(tag of tagArray){
tags.push(<a href={"?tag="+tag} className="postTag">{tag}</a>);
}
It works after replacing it with this:
for(var i in tagArray){
var tag=tagArray[i];
tags.push(<a href={"?tag="+tag} className="postTag">{tag}</a>);
}
just import 'core-js/es6/' to your index.js or main entry file
