Is React/Redux way of building apps similar to Elm architecture?

I'm asking this question NOT for comparison purposes or in order to decide which one the best. It's just curiosity.

I wonder is there any similarities between how apps build in React/Redux and Elm ? And if there any differences ?

By reading interview with Dan Abramov I know that Dan and Redux core team first created Redux and then discovered that Elm Architecture is very similar.

I wonder are similarities just end on how Redux designed or they go further ?

I know this kinda broad question, but in general I'd like to know how many common ideas between React/Redux and Elm. Are they same ideas and just implemented differently or they different in some important way?

Thank you for any explanation/clarification :)
