Creating functions with Ruby is both similar and different from other languages. This is because of Ruby’s design to be simple to use/program with, but in it, some people may find certain things difficult to handle. A Simple Function Like with Python, you’ll define a function using the def keyword. An example can be seen…
In Ruby, an array is an ordered collection of objects, which can hold multiple data types, including numbers, strings, other arrays, or even objects. Of the languages we’ve looked at, it is most similar to lists in Python, where you can store dynamic types, and they are dynamically sized. There are a couple of ways…

Strings are a common data type we find and use in many programming languages. As we are used to using Strings, we find that there are several common methods/functions for working with strings. Some we’ve already seen, but here are also some new ones. size: the size operator lets us see how big a string…
The Ruby method each allows you to iterate over a list of items. This is essentially a for-each style of loop and is like JavaScript’s each method. Notice that the iterative value is placed inside of two pipe (|) characters. You don’t have to put everything on one line. In fact, you can’t if you have multiple…

Classes do not have to be in a separate file as you can see from the file below. Let’s look at a class, then break it down. Class Definition As with most languages, you use class to define your class definition, and class names typically start with a capital letter. As with conditions, and other…
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…
