Example for issue #11780 at webpack

UPD You need Node.js 14.6.0+ to reproduce the issue

git clone https://github.com/BATCOH/webpack-profiling-example.git
cd webpack-profiling-example
npm install
npm run build

Drag and drop generated events.json into the Chrome DevTools Profiler.

You can also take events.json from events/${node_version} folder of this repo.

build.sh

Weird shell script that uses Nodebrew to produce two events.json (for node 14.5.0 and node 14.6.0), and jq with jd to somehow compare them.
