Basically, in your case the value is not valid JavaScript identifier, so you have to use square brackets notation:

"An object property name can be any valid JavaScript string, or anything that can be converted to a string, including the empty string. However, any property name that is not a valid JavaScript identifier (for example, a property name that has a space or a hyphen, or that starts with a number) can only be accessed using the square bracket notation. This notation is also very useful when property names are to be dynamically determined (when the property name is not determined until runtime)."

You can have a look at this article: Working with objects
