What are your plans for the next year — what to learn and master?

In the upcoming year, I plan to deepen my knowledge in high-performance systems in Go, especially in optimizing concurrency and profiling. I want to master advanced design patterns and explore new language features such as generics and improvements in the standard library.

I also plan to study the integration of Go with modern cloud technologies and containerization (Docker, Kubernetes) for more efficient deployment and scaling of services.

An example of a topic I am studying is using generics to write universal functions:

func Map[T any, R any](items []T, f func(T) R) []R {
    result := make([]R, len(items))
    for i, v := range items {
        result[i] = f(v)
    }
    return result
}

This will allow writing more flexible and reusable code.
