Slices are one of the most important data structures used in Go. In this post, we will look at how to concatenate slices. We will start by explaining the general concept of concatenation, then we will look at examples of concatenating two or more slices in Go. Finally, we will build functions that can help […]

This post will discuss the various ways to add elements to a slice. Appending an element adds it to the end of the slice, whereas prepending it adds it to the beginning of a slice. It is also, of course, possible to add an element at any position in between. We will finish by looking […]

I’ve written in the past about how to reverse the order of all the elements in a slice, but today I’m going to discuss some of the ways that elements can be removed — in other words, deleted — from a slice in Go. When looking at the various ways to remove one or more […]

It’s been a long time coming and it’s caused a certain degree of controversy among Gophers, but now we know, at last, that it’s really happening. Generics have been included in a beta version of Go 1.18, which was just released this week. What Are Generics? In a strictly typed language like Go, every argument […]

Slices in Go are equivalent to the data structures known as dynamic arrays or vectors in other programming languages. They simply allow us to collect data of the same type together, making it easy to access and pass around. Sometimes you may want to reverse the current order of your data, and this post discusses […]
