CRA stands for create-react-app. This repo is browserify plugin. You probably wonder how I get here with CRA, which in turn uses Webpack. Here is the story:
I'm trying to make react-mapbox-gl work with CRA. react-mapbox-gl is react component for mapbox-gl, which in turn use browserify and webworkify. I'm not sure if this problem of webworkify or not. I suppose because I see blobs and workers in stack trace. Tell me if this CRA/Webpack/Mapbox error.

Related: alex3165/react-mapbox-gl#231
Note: prior CRA 1, for example 0.9.5, it worked fine.
To reproduce problem:
git clone https://github.com/stereobooster/react-mapbox-gl
cd react-mapbox-gl
git checkout webworkify-problem
cd example
yarn
yarn build
# yarn global add serve
serve -s builddavidascher commented
I hadn't noticed this bug when I started down this rabbit hole myself. See mishoo/UglifyJS#2011 for a long parallel path.
TLDR: it seems this (https://github.com/substack/webworkify/blob/master/index.js#L63) code is violating some assumption that uglify is making, I suspect it's the same problem with browserify.
@stereobooster note: CRA 1.0.7 has this problem worked around, but it seems to me there's still an incompatibility between webworkify and uglify's comparisons compression assumptions.

webworkify is not the problem.
