Asset pipeline error using uglifier

[robban]

When deploying to heroku, I got an error when rake assets:precompile ran:

ExecJS::RuntimeError: SyntaxError: Invalid assignment JS_Parse_Error.Object.defineProperty.get((execjs):3538:621)

I managed to solve this by replacing

config.assets.js_compressor = :uglifier

with

config.assets.js_compressor = Uglifier.new(harmony: true)

Is there some ES6 code in rails_sortable that makes uglifier fail without the harmony setting?

Oh, sorry. I didn't know Destructuring assignment was a part of ES6.

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment

I will fix it later. Thank you.

rails_sortable-1.2.1 was pushed to rubygems.
