Google maps Ya, Za and $a

Question

I am using google maps to find lat and lng of the clicked location. After stringifying the javascript event object, I found

{"latLng":{"Za":25.800813110356653,"$a":78.7055234375},"pixel":{"x":689,"y":336},"va":{"x":183.96837222222223,"y":108.99927181860028}}

So Za is lat and $a is lng now.

Though two days ago, I was using exact same code and getting the same object as:

{"latLng":{"Ya":25.800813110356653,"Za":78.7055234375},"pixel":{"x":689,"y":336},"va":{"x":183.96837222222223,"y":108.99927181860028}}

What bothers me is that they have changed the object names overnight. Why do they do this and is there any reliable way to find latitude and longitude instead?

Answer 1

Internal names will change with code changes: if another token is introduced then a variable which was minifed as Ya may end up being Za.

You should never access internal references. Always use documented methods.
