I am just going through the [Elixir and Phoenix Bootcamp](https://forum.elixirforum.com/t/the-complete-elixir-and-phoenix-bootcamp-udemy-course/2271) course and in my notes I have written:

> **Structs**

Just like Maps but with 2 advantages:

> 

- Can be assigned default values
- Additional compile-time checking of properties

> If we know the properties we are going to be working with we will use a Struct instead of a Map.
