Ruby has become a popular choice for back-end development, and there are a few good reasons for this.

First, Ruby's coding style is simple and easy to read. This helps developers write clear and understandable code. When a team works together, clear code makes it easier for everyone. For example, setting a variable in Ruby is straightforward, like this:

username = "developer"

You can see how simple that is. This clarity is important, especially in big projects.

Next, Ruby is closely linked to a tool called Ruby on Rails. This tool follows a rule called "convention over configuration." This means that, in most cases, Rails automatically understands what settings to use without needing a lot of extra instructions. For instance, to create a new Rails application, a developer just needs to type one command:

rails new myapp

That's quick and easy!

Finally, Ruby has a strong community and many helpful libraries, known as gems. These gems can save time when building applications.

With all these advantages, it’s no wonder that Ruby is still a favorite choice for back-end developers.
