async/await syntax is currently accessible via typescript if you compile
using --target ES2015 or above.
Disabling the promise manager will break Protractor's debugging and
browser.pause(). However, because your tests won't be using the promise
manager, you can debug them using standard Node debugging tools. For
example, you can use the Chrome inspector to debug the test in this
directory (protractor/exampleTypescript) with npm run debug. You should see something like
Debugger listening on port 9229.
Warning: This is an experimental feature and could change at any time.
To start debugging, open the following URL in Chrome:
chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=127.0.0.1:9229/f48502b0-76a3-4659-92d1-bef07a222859
Open that URL in chrome, and you'll get an inspector that can be
used to debug your test. Instead of browser.pause, you can add debugger
to create a breakpoint. Note that sourcemaps don't work in the inspector
in Node v6, but do work in Node v7 (due to nodejs/node#8369).
