Let’s take a closer look at Go’s slice notation, emphasizing how slices relate to their underlying arrays.

By now you’re probably aware of functional options, in that they’re a nuanced approach to object configuration that provide flexibility, extensibility and readability that in my opinion, traditional setters can’t match. That said, a co worker of mine asked why I am using them over traditional setters as they see most examples just setting a field.
Well let’s explore functional options through practical examples, understand their advantages over traditional setters, and see how they can be composed and used to enhance testability.
Hello, my friends and fellow Go developers
There’s been an engaging discussion on the efficiency of HTTP routers in Go. It’s inspiring and wonderful to see such detailed analysis and passion!
That said, I’d like to add my perspective that personally helps me focus on what impacts our applications the most and where I should spent my precious time.
Relative Importance of Router Performance: In our web applications, the HTTP router plays an important role right?
