Demand for Ruby programmers is high because it's a relatively new, cross-platform language. This online video for developer and programming foundations will cover the basics of the Ruby programming language. You'll see examples of the code that will provide insight into how the language is structured, and how easy it is to learn in comparison to more complex languages.
Let's take a look at one of the newer languages on the list, Ruby.…This was developed in Japan in the mid 1990s and most people would consider it a…very pure object oriented language.…In Ruby everything is an object, even variables that might be considered…primitives in other languages like Booleans or integers.…Everything is an object.…It's a high level garbage collected language.…We don't really need to think about memory management and it's…completely interpreted.…We don't need a compiler for Ruby.…We do need an interpreter.…
It doesn't compile to intermediate language like Java or the .NET languages.…Most people find it very easy to approach.…There isn't a lot of prerequisite knowledge required to get started with Ruby.…So it's fairly friendly for beginners.…The question is what it used for?…Well, it is a cross-platform language.…There are installers and interpreters available on every OS and you'll actually…find it built into the last few versions of Mac OS X. It's probably become most…famous recently for it to use in what's called Ruby on Rails.…
