I'm really interested in finding out about ES6 Template Strings and have been doing a little bit of reading on the feature.
However now that Chrome Canary does not support it (although maybe I'm wrong about that!) is there anywhere/anything I can use to try out this new functionality? Any browser beta around that does?
I've already enabled Experimental Javascript Features inside chrome://flags
It's only supported in Traceur at the moment.
You can play with it in their REPL.
es6fiddle.net doesn't seem to support it yet, but probably will soon.
Mozilla is working on it so expect to see it in nightly builds soon as well.
