fix: added a typeof check to prevent crash without internet connection

When there isn´t a internet connection, the app crash.

I think we should check also if maps in google is available.
Rewriting check to if(!google || !google.maps) should be enough.

I check your code and does't works. I getting: google is not defined.
if you will check remember delete browser cache

@mauriciosfriso Sorry for wrong example, my mistake, conditions in my example should be reversed.
if(google && google.maps).

[mauriciosfriso]

@Simek I see your mistake, but anyway it's not works. I keep getting:

google is not defined

therefore I check the google's type

sorry for my English

[Simek]

I've dig a little bit into this problem. Seems that google is set to be an identifier until script loads. This causes !google check to throw "undefined" error so your code comparing type is correct way to check this. And don't worry about your english. It's fine.
