you can't check JSON for whether or not they're strings like regular variables?

this is not working for me...

 if (typeof propName === 'string') {
in this example,

to grab for the "joined" property (which contains three values, so had to loop again...)

I had to "cheat" and do

 if(PropName === "joined") {

but the line I really wanted to use, namely

 if (typeof propName === 'string') {
was ignored.....

but in my real situation need very much to detect whether a value is a string or an object... I assume this is pretty standard JSON stuff.....

(in my real situation I need to check the Value, not the Prop name... and it's the exact same problem......

this is ignored.....

 if (typeof propValue === 'string') {

thank you....
