I was pleasantly surprised to hear that ECMA5 will now be supported in the Helsinki release of ServiceNow. For most people this won't mean much of anything. I was excited to hear about the change since there were a few things I had noticed missing when working with server side javascript. Most notably the indexOf operation on arrays.

Today I was testing out some functionality in Helsinki and ran into a really ugly error with something that worked perfectly fine in Geneva. 

After a little digging I discovered that the format for JSON was updated as well and is more strict now. So if you're doing any parsing of JSON in ServiceNow, make sure your property names use double quotes instead of single quotes and you'll save yourself some trouble. 

As an example, this:

{'incident':'caller_id'}

is incorrect. Instead you should use this:

{"incident":"caller_id"}
