Safari history bug in Tutorials & ES5/ES6 Tutorials

[Daniel Zen]

I've been working on JavaScript ES5/ES6 version for the Tutorials of "Tour of Heroes".

Besides Chrome, I have been spending some time in Safari because it still doesn't support arrow functions and therefore is a good browser to test ES5 code. I spent some time making what I believe is a pure ES5 version of the Tutorial:

     Angular 2 ES5 Example - Tour of Heroes: Part 5

and it works fine in Chrome. However, in Safari, I have a problem when I click the "Back" button in the hero-detail.component. It calls window.history.back() at which point it successfully navigates the route, but the state of the component is lost. Not being sure if this was a bug in Safari, or my code, I figured I would try the regular TypeScript version in Safari:

    https://angular.io/resources/live-examples/toh-5/ts/plnkr.html

And sure enough, the problem remains. 

On a separate note, I'm still interested in helping write ES5 & ES6 documentation for Angular2, and would love a response to my first pull request.

I completed a pure ES6 version using Babel:

     Angular 2 ES6 Example - Tour of Heroes: Part 5

babel-core & babel-runtime are mapped automatically by http://jspm.io/system.js. 

The curious thing is, it has the same history bug as Safari. It successfully navigates the route, but the state of the component is lost. Strange. 

Anyway, I've been trying to offer to write ES5/ES6 documentation, but haven't received any responses yet through any channels. Any suggestions on where I should reach out?

Thanks,

Daniel
