[OpenLayers-Users] specifying options for OL class properties--when to use quotes?

[Erik Uzureau]

it was explained to me at some point in life that the "proper" JSON
notation was
putting quotes (single?) around the key names, ie:

var foo = { 'keyname': keyvalue };

...and I have been trying more or less to do that ever since. although
clearly it is
functionally equivalent to

var foo = { keyname: keyvalue };

(excepting where keyname is a js reserved word, as specified in eric
and cr5's responses)

...if the first one is "proper" for JSON, maybe it's proper for JS as well?

bottom line: it doesn't  matter.
