The other one is a new shorter syntax, using empty brackets, that does the same thing. Spectrum's source frequently uses fragment-returning components for this purpose. Fragments can be used using 2 syntax, the first one is using React.Fragment which weve used multiple times above. React Fragments are a neat little feature that were released late last year with React v16.2.0 it’s a pretty small feature, but just knowing about the existence of them can save developers a huge headache when running into some very specific.
