15 Outstanding Ruby Language Features You Should Know.

15 Outstanding Ruby Language Features You Should Know.

Are you wondering why Ruby language is so popular and their features are just outstanding?

The main motive of creating the Ruby programming language is he wants to make the Ruby language natural, not simple and due to this, he added all the blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

The Ruby language creator Yukihiro “Matz” Matsumoto, says about the language:

Ruby is simple in appearance, but is very complex inside, just like our human body.

If we talk about the popularity of the language then after its public release in 1995, Ruby has drawn devoted coders worldwide. In 2006, Ruby achieved mass acceptance. That is amazing!!!

Now, let’s look at the 15 outstanding Ruby language features you should know while learning the language or if you are thinking to start learning.

Before that, I have already made an article on the Ruby language where I have explained everything about the language such as some important concepts, history, features, resources to learn, career opportunities, and many more.

Here’s the article link: 10 Amazing Ruby Programming Language Features

1. Ruby is Concise in Nature

Ruby is concise in nature, very simpler and light to practice language that provides you a manageable syntax, and doesn’t have to write a lot of code for developing any application.

We have already discussed how to write the Hello World program. Simply you have to write one line of code whereas in another language we have two to three lines of code.

For e.g.

Ruby language features

It’s a simple hello world program that is written in the C++ language. Now let’s see the same program in the Ruby language.

puts "Hello World"

The same Hello World program is written in just one line of code. That is amazing!!!

2. Pure Object-Oriented Ruby Programming Language

The Language is a pure object-oriented programming language. Every value has its own object and every object has its own classes.

Each and every line of code has to give its own properties and actions.

Basically, the properties are known as instance variables, and actions are known as methods. Ruby is totally influenced by Smalltalk language by giving methods and instance variables to all of its types. The Rules which are applying to objects totally apply to the entire Ruby.

Ruby’s pure object-oriented approach is most commonly demonstrated by a bit of code that applies an action to a number.

5.times { print "We *love* Ruby -- it's outrageous!" }

In many languages, numbers and other primitive types are not objects. Ruby follows the influence of the Smalltalk language by giving methods and instance variables to all of its types. This eases one’s use of Ruby since rules applying to objects apply to all of Ruby.

3. Objects & Methods

Here’s another thing that’s great about Ruby every piece of data that your program works with has useful snippets of code.

It is already attached to it and Ruby pieces of data are known as objects and snippets of code attached to objects are known as methods.

Basically, other programming languages also have objects and methods too but in Ruby, it’s easier to make use of them.

For e.g. Let’ take an example where we have a list of numbers and then sort that list. Firstly, we will see In Java language.

Sorting in Java

After that, we will see through the Ruby language.

In simpler terms, you don’t have to load the modules yourself what you need is already loaded for you.

This is another example of a situation where the designers of Ruby have a choice to make things easier and more pleasant for the programmer.

4. Ruby is a Very Flexible Language

Ruby is one that programming language that never restricts their coders. We can efficiently remove or redefined the fundamental parts of it. The language never tries to restrict the coder and always allows users to freely develop its parts.

For example, addition is performed with the plus (+) operator. But, if you’d rather use the readable word plus, you could add such a method to Ruby’s builtin Numeric class.

class Numeric
  def plus(x)
    self.+(x)
  end
end

y = 5.plus 6
# y is now equal to 11

Ruby’s operators are syntactic sugar for methods. You can redefine them as well.

5. Mixins

As we all know that Ruby is an object-oriented programming language but it doesn’t support Multiple Inheritance

It supports Single Inheritance and one more feature i.e. Mixins. 

Mixins determine that it is a set of code that is enclosed up in a module(modules are collections of methods) that a class can combine or eliminate. Classes can have more than one Mixins.

Classes can mixin a module and receive all its methods for free. For example, any class which implements the each the method can mixin the Enumerable module, which adds a pile of methods that use each for looping.

class MyArray
  include Enumerable
end

Generally, Rubyists see this as a much clearer way than multiple inheritances, which are complex and can be too restrictive.

6. Popular Ruby on Rails Web Framework

Most importantly Ruby has the powers of Ruby on Rails which is arguably the world’s most popular Web Framework. Ruby on Rails is an open-source software used to build web applications.

Rails is a framework used to create websites using the general-purpose programming language Ruby. Ruby ranks amongst the top ten programming languages predominantly because of the voguishness of Rails.

Airbnb, Github, Fiverr, and Kickstart uses Rails to help run their websites and many other companies.

7. Dynamic Typing

Ruby provides you dynamic typing feature that is one of the countless wondrous Ruby language features. Dynamic typing determines that the majority of type checking is done at the time of run-time, not in a compile-time.

It helps developers in a project when they wanted to do some changes in their applications in the additional stages such as we can change the type of variable, and many more things.

8. Duck Typing

Duck typing” means: just try the method (function call) on whatever object comes in rather than checking the object’s type first to see if that method is even a valid call on such a type.

def func(a):
    a.method1()
    a.method2()

When the object comes into the function func(), the function shall try (at run time) to call any methods specified on this object (namely: method1() and method2() in the example above), rather than first checking to see if a is some “valid type” which has these methods.

So, it’s an action-based attempt at run-time, NOT a type-based check at compile-time or run-time.

Now look at this silly example:

def func(duck_or_duck_like_object):
    duck_or_duck_like_object.quack()
    duck_or_duck_like_object.walk()
    duck_or_duck_like_object.fly()

Hence is born the ridiculous phrase:

If it walks like a duck and quacks like a duck then it is a duck.

The program that uses “duck typing” shall simply try whatever methods are called on the object (in this example above: quack()walk(), and fly()) withOUT even knowing the type of the object!

It just tries the methods! If they work, great, for all the “duck typing” language knows or cares, IT IS A DUCK!–because all the methods worked on it.

9. Visual Appearances

Basically, Ruby language has very limited punctuation and they mainly use English keywords. But still, there is some punctuation that is used to decorate Ruby.

Although Ruby doesn’t require variable declarations it uses simple naming conventions to denote the scope of variables.

  • var could be a local variable.
  • @var is an instance variable.
  • $var is a global variable.

10. Saves Developers Time

Although other programming languages such as C/C++, Java, Python, JavaScript, etc are some of the most beneficial languages to build a project in comparison with Ruby it saves a lot of developers time while doing typing.

That’s why the developers choose the Ruby language to create some incredibly innovative software. like Chef which Facebook uses to automate its server configuration or Sass which helps to provide styling for the websites.

11. Exceptional Handling Features

The language also presents you exceptional handling features which another language has such as Java or Python. That eases the programmer to handle errors easily.

12. Platform-Independent Language

It’s a platform-independent language. It implies that Ruby interpreter is available for every popular platform such as Windows, Mac OS, and Linux.

13. Popularity

Ruby is popularly applied in Web Development, e-commerce, content management, custom database solutions, and prototyping.

14. Garbage Collector

Ruby language fully supported garbage collections. Garbage collection relieves the programmer from performing manual memory management where the programmer specifies what objects to deallocate and return to the memory system and when to do so.

15. Remaining Features

Some features are left i.e. Ruby has reserved keywords, it’s a Case sensitive language, Performance and Security, and many more. Besides this Ruby has pretty great community support.

Wrapping Up

Currently, Ruby language is one of the best languages and comes under the top 15 WANTED programming languages across the world. That is Insane!!!

While if you are learning or planning to learn the Ruby language then you must read all the amazing features that really assist you to understand the potential of the language.
