v3 breaks Webpack / UglifyJS bundling process

[natorojr]

I've been using the stringify-object package for quite some time in both my Node projects and Web projects. Recently, I upgraded from v2.4.0 to v3.1.0 and that broke my Webpack build process as follows:

ERROR in app.22a5f0a6.js from UglifyJs
SyntaxError: Unexpected token: operator (>) [../~/stringify-object/index.js:6,0]

Seems like this line is the culprit.

If I change that line to regular function syntax notation (instead of ES6 arrow syntax), it seems to fix the problem.

Any ideas why Uglify would complain there?

I use stringify-object heavily for debugging purposes throughout my projects, so I'd love to get this fixed.

Uglify doesn't support ES2015. It's up to you to transpile with Babel or stay at the older version.
