learning programming ruby can make us handle everything or it is a first step
If you are interested in learning some programming, then Hackety Hack is an easy way to do it. It uses real ruby lessons to teach how programming works which you can use in just about any other programming language.
It's a good first step, and you learn skills that can be used elsewhere.
Does that help?
I wanted to know the same thing when I first started to program.
If I understand you correctly, you want to know if ruby is a good language to learn.
Ruby is a good general purpose programming language. It is "suited" toward a large variety of tasks. In fact, there are very few types of programming tasks that Ruby cannot be used for. It really is a great place to start.
However, as you asked specifically, learning Ruby won't enable you to handle everything. There is no single programming language that will. However, knowing ruby will certainly help you to learn whatever else you need to know.
