ES2015 support for old browsers

[mojoaxel]

A lot of browsers do not jetzt support all ES2015 features yet (e.g. for...of).
You should use something like bable.js to also older or more alternativ browsers.

Which part of the js code are you refering to?

[mojoaxel]

There are multible for-of loops (e.g. in map.js:73).

Also you use some modern CSS3 features, what is cool, but also not well supported. (e.g. the css calc function map.html:14)

This an issue e.g. in Chromium 22 on Debian 7
