This post will discuss what a zero value is and how it can be relied upon to give some default state to initialized variables. It’s important to know the zero values for each of the basic data types in Go, in order to use them in your own code, so we will also provide a […]

This post will look at various ways to reverse a string in Go, a fairly common task that isn’t explicitly handled by the standard library. We will start by looking at some basic examples using Java and the Linux command line, then we will go through various ways to code solutions to the problem in […]

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 […]

Okay, I’m biased — it’s my task runner — but hear me out. This post will start by discussing what a task runner actually is and exploring how it works by building a very basic version of one in Go code. Then we’ll look at some example tasks that can be completed with the help […]

Sometimes you want to read a file that contains many lines of text or a list of structured data and you want to process each line individually, rather than working with the entire content of the file at once. This post will discuss various ways to read a file line by line, looking first at […]

This post will explain what hash functions are and how they’re used. We will then go on to look at some examples of hashing algorithms in Go code. Finally, we will look at importing external packages that export hash functions, including from the standard library. What Is a Hash Function? A hash function takes data […]

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 […]
