syntax errors in IE

[hbi99]

Which version?

[thedimm]

Latest v2.1.2
Tried defiant.js and defiant.min.js and I got syntax error in IE when I include them. OK in Chrome.

I mean which version of IE :-)

Sorry :)
IE 11.0.9600

the same with me

The specific error occurring in IE11 (I have the issue in 11.0.9600):
SCRIPT1046: "Multiple definitions of a property not allowed in strict mode"
File: defiant.minjs, Line: 6; Column 4764

When I dive a bit deeper, it looks like IE is throwing security errors with this line (759 in defiant.js):
worker = new Worker(url.createObjectURL(blob));

I've seen conversations about this issue in other scripts, too, like leaflet.js:
Leaflet/Leaflet.VectorGrid#58

I'm also seeing errors in IE 11:
Object doesn't support property or method 'selectNodes'

@designbymichael
I encountered a problem with Web Workers in IE.
This seems to be a known issue as well and I haven't been able to come up with a solution.
