Working with a Map in Go is like Dictionaries in Python, or Maps in Java. A Map stores information as key/value pairs. This is a nice thing about data structures, they are often found in other languages. Defining the Map When you define one in Go, you need to define the variable as a type…
Installing Ruby is relatively simple. There is an install page as part of the Ruby documentation: https://www.ruby-lang.org/en/documentation/installation/ While they would prefer you to have a Unix, or Unix like environment, you can scroll down to find the best way to install this language runtime software. I personally went to the Ruby Installers section of the…
Ruby is a high-level, interpreted programming language that was designed to make coding as enjoyable as possible. Created by Yukihiro Matsumoto in the mid-1990s, Ruby prioritizes readability, simplicity, and productivity. The language is dynamically typed, object-oriented, and often praised for its clean, expressive syntax, which resembles natural language. Ruby is particularly popular in web development,…
Rust is a systems programming language that’s designed to combine safety, speed, and concurrency. Created by Mozilla in 2010 and currently maintained by the Rust Foundation, Rust aims to overcome some of the biggest challenges faced by programmers in languages like C and C++. Its primary goal is to eliminate common programming errors like null…
In Go, arrays and slices are both used to store sequences of elements, but they have important differences in structure, flexibility, and use cases. Working with Arrays Arrays in Go are similar to C/C++ where they are of a fixed length, and all members of the array are of the same data type. Sometimes this…
Go, like all modern languages, has functions. As we saw in the example where we built our first program in Go, functions start with the func keyword. To create a basic function that doesn’t take any parameters and doesn’t return a value, is simple: If you want to pass parameters you put them in the…
Performing Math in Go is like many other programing languages in many ways. Of course, the standard mathematical symbols apply: Operator Description + Addition – Subtraction * Multiplication / Quotient % Remainder & Bitwise AND | Bitwise OR ^ Bitwise XOR &^ Bit clear (AND NOT) << Left shift >> Right shift (logical) The Math…
Now that you have your first program in Go, and you know that it is installed correctly, let’s look at modifying some code to get a more robust program. Declaring Variables Go is a statically typed language (i.e. it is defined when variables are created and those variables cannot change) that does not permit operations…
