# Functional Programming With Slices

This post will explore the programming paradigm known as functional programming and discuss what restrictions it places on programmers, as well as how it helps in the process of developing and structuring code. We will then go through some practical examples of functional-style code written in Go, specifically looking at how generic functions can be […]

# How to Concatenate Slices

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 […]

# Adding Elements to a Slice

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 […]

# Removing Elements From a Slice

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 […]

# A Super Speed-up With Binary Search

In any programming language, there are two main algorithms used for finding a given value in an array: linear search and binary search. (Just to note: in Go, we generally use slices rather than arrays, but I’ll use those two terms interchangeably in this post, just for the sake of simplicity, since everything that I […]

# Drawing an Awesome Chessboard in Go

Since chess is one of the oldest games in the world, the black-and-white chessboard is an instantly recognizable design. It originated in Asia around 1,500 years ago. In this post, we’ll create an image of a chessboard in the Go programming language. But we’ll gradually think through the problems involved before we actually draw it. […]

# Reversing a Slice

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 […]
