How to display an object in jsx?

Question

JavaScript

I get into the variable structure oject of the form
firstName:"Ivan"
lastName:"Ivanov"
The fields of the object can be different. and now I want to pass its parameters to enumerations in the component, if with arrays it is possible to display everything through map, then what about objects?
Here's how the array works

return (
        entities.data.map(entity =>
          <Entity requestDeleteEntity={requestDeleteEntity} entity={entity} key={entity._id}  />
        )
      );

The point is that at the input I have a json like {'label 1' : 'value 1', 'label 2', 'value 2'} and so on. I need to output these data in the form of inputs and the user can also add an arbitrary number of inputs key - value.
