What Is Ruby Used For?
If you hang out in any of the web development communities, there’s no way you don’t hear about the Ruby programming language.
What is Ruby?
Here is how the official Ruby website describes it.
A dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.
Back in 2007 when I first heard about Ruby, the alternatives were Perl, Java, and PHP. So what attracted me to the language was actually the fact that I could understand what a piece of code was about without knowing much about programming.
And now, after more than a decade of using it, I still think Ruby is the easiest language you can learn. But it’s not just that.
With Ruby, you can very easily play with ideas and see if they have a chance of working in the real world.
The fact that it is a very permissive language, allows you to try things out even if they are just rough ideas. You don’t have to be strict about your programs if you don’t want to. You can postpone that.
What can you do with Ruby?
You can use Ruby just like you would use any other general-purpose scripting language. A few examples would be web applications, web servers, system utilities, database work, backups, parsing, even biology and medicine.
So you can use Ruby to do a lot of things. It’s not going to be good at all of them but at least it will allow you to get started, test some ideas and help you figure out if you need a more specialized language or not.
