In addition to the basic programming logic that Ruby has, it also has a few weirder forms of logic it can employ. Single Line Conditions Ruby allows for single line conditions where it is almost like a short hand. However, doing so may seem backward to normal logic, because the true block goes first. Consider…
In Ruby, you’ll find that all of the standard logic operators that most languages have, are supported. Symbol Meaning < Less than > Greater than == Equals != Not equals >= Greater OR equal to <= Less OR equal to Conditionals Of course, conditionals such as an if statement are also possible within Ruby. Similar…
Ruby’s variables are dynamic, meaning you don’t need to declare their type explicitly. This is similar to JavaScript, and Python, but vastly different from C/C++, Java, TypeScript, and Go. Types of Variables Ruby is a little different in how it handles different types of variables, defining them by different prefixes. Local Variables Notice how Ruby…
As with most languages, we always want to start with a “Hello World” program. Remember, this is to make sure everything is working, as much as it is to learn the programming language. For simplicity’s sake, we’re going to use the online editor: https://www.jdoodle.com/execute-ruby-online or https://www.onlinegdb.com/online_ruby_compiler You will notice right away that in Ruby, we…
Once you’ve installed Ruby on your machine, you want to get it ready to work in Visual Studio Code. You will want to install an Extension. So go to the Extensions menu, and search for: “Ruby LSP”. There use to be a Ruby extension, however it was deprecated, and this one was suggested. I’ve installed…
One of Go’s initial design requirements was to make it easy to create multi-threaded applications. While many languages support multi-threading, it’s not always easy to implement. Go wanted to make it easy to do this. Consider the following code where it runs sequentially. If you run this, every function call to PrintHello() has to complete…
Go doesn’t have classes like Java or C++. Instead they have something similar to a struct that the C language has. In fact, they even call it a struct. Unlike a class, where you encapsulate your data, having it private, instead here, the attribute data is all public. Secondly, the methods are not built into…
In Go, packages and modules play a crucial role in organizing and managing code. Here’s a breakdown of their differences and how they work: Packages: Definition: A package is a collection of Go source files in the same directory. It acts as a namespace for the code within it. This is what we will mostly…
