How to implement the shorcut JavaScript method of setting a default value to something that hasn't been set e.g var1 = msg.payload || 'default' type construct
This can be done explicitly by testing if the property exists and then check to see if it is 0, an empty string or boolean false value
but can also be done more compactly by utilising the JavaScript function block
