One of the coolest things about Ruby is that you can write clear yet concise code. This is especially useful when you want to automate repetitive tasks using scripts. To understand how to use Ruby in your scripts, in most cases you can simply look at the standard help for the ruby command, such as ruby -h or man ruby. You can also pass arbitrary code using the -e option, for example:

Have you ever forgotten the name of an operator while working with Ruby? If so, you’re not alone, I also forget their names from time to time. And that’s why I have the following resources in my bookmarks:

https://github.com/anildigital/ruby-operators/blob/master/public/operators.json
https://www.visualmode.dev/ruby-operators
https://github.com/JuanitoFatas/what-do-you-call-this-in-ruby
https://kddnewton.com/2023/07/20/ruby-operators.html On these websites, you can find new operators (whose existence you never even knew existed) and alternative names for well-known operators. If you have some free time right now, be sure to check these resources out. You’ll find some fascinating reading.

Ruby evolution

To better understand any technology, it is not enough to study the documentation, read books and articles for the current version. It is necessary to begin examining the technology from the origins of its creation and follow it chronologically to the latest version. It is important to understand when, what, and starting with which version a particular feature was added or removed. Based on this principle, to better understand the Ruby language, I would recommend referring to the documentation, books, and articles for older versions. A starting point and a great helper in this regard is the rubyreferences resource, which contains all the significant changes to the Ruby language since version 2.4.

If you’re an experienced developer and want to brush up on your Ruby knowledge, check out the cheat sheets periodically. Refer to the manuals only when you don’t understand something in them or you’ve forgotten it (or maybe you didn’t know it). This way, you can quickly find gaps in your knowledge and fill them as quickly as possible. Here’s a list of cheat sheet websites that I always keep in my browser bookmarks:
