Reading and Writing YAML

This post will discuss what YAML is and how its syntax works. We will then move on to a simple real-world example, so you can see how YAML looks. Finally, we will learn how a program can be written in Go code that is able to read and write data formatted in YAML. What Is […]

Golang Zero Values (0 and Beyond)

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 […]

Reversing a String

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 […]

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 Read a File Line by Line

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 […]

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 […]
