Do we have access to Map/HashMap?

I tried including including #include <HashMap.h> but it said library not found. And Map<String, Person> profiles = new HashMap<String, Person>(); says Map/HashMap are not defined.

So does Particle support hashmap?

How did you try to include that library? Did you use the library system, or did you add the files manually?

I just included the line #include <HashMap.h> (and also tried #include "HashMap.h") at the top of my profile file.

And where is the IDE supposed to get those files from? (Including things like that won’t work for any library)

It looks like this is an Arduino library that has not been brought to Particle world yet. It can be found here:

I think that code would just work in Particle or you could use std::map instead.
