What are the differences between structs and maps in Go?

What are the differences between structs and maps in Go?

In Go, structs are used to create complex data types with fields, while maps are key-value pairs for dynamic data.

Can you give me an example of when to use a struct instead of a map?

Sure! Use a struct when you have a fixed set of fields, like a 'Person' with 'Name' and 'Age'. Maps are better for dynamic data.

Are there performance differences between using structs and maps?

Yes, structs are generally faster for fixed data due to their static nature, while maps can be slower due to their dynamic allocation.

How do I define a struct in Go?

You can define a struct in Go using the 'type' keyword, like this: 'type Person struct { Name string; Age int }'.
