Description

Certain Javascript expressions fail to produce expected output after building project using es6-bundled or es5-bundled.

Versions & Environment

Steps to Reproduce

  1. Create a polymer-2-application project using polymer init
  2. console log following expressions: !(true && !undefined) and !(!undefined && true) in one component.
  3. Use following polymer.json. This is for es6-bundled.

{ "lint": { "rules": [ "polymer-2" ] }, "entrypoint": "index.html", "sources": [ "src/**/*", "bower.json" ], "builds": [ { "preset": "es6-bundled" } ] }

  1. Run polymer build
  2. cd build/es6-bundled
  3. polymer serve and check your console.

Expected Results

Expected results for expressions !(true && !undefined) and !(!undefined && true) is false. I get false for both these expression when I don't build my application.

Actual Results

I get: undefined for !(true && !undefined) false for !(!undefined && true)
