Echo JS 0.11.0

Did you read the whole article? He mentions reduce towards the end.

Agreed, seems shady...

Very nice, I'm not a big fan of ES6 Classes but the code is super clean.

You mention IE9+ support, however the code uses classList which is supported in IE10 not IE9...?

This reads more like a short story rather then actual tips for interviewing. What are the chances that every question would be strictly ES6+

Please let me know if you have any comments and/or suggestions.

Keep up the great work :-)

Is the w3schools slide supposed to be sarcastic? (I really hope so...)

Why in the world would I use something like this and not SASS/LESS or even OOCSS which could be managed in a similar way?
