Ruby for Beginners

Ruby is a high-level, interpreted programming language known for its simplicity and productivity. In this guide, we will go through the basic concepts of Ruby programming.

Syntax

Ruby syntax is easy to read and write. Here is an example of a basic Ruby program that prints "Hello World!" to the console.

puts "Hello World!"

Example

Let's take a look at another example where we define a method that takes two arguments and returns their sum.

def add_numbers(num1, num2)
  sum = num1 + num2
  return sum
end

puts add_numbers(5, 10)

Output

The output of the above program will be:

15

Explanation

In the above example, we defined a method called add_numbers that takes two arguments num1 and num2. We then assigned the sum of num1 and num2 to a variable called sum, and returned the value of sum. Finally, we printed the result of calling the add_numbers method with arguments 5 and 10.

Use

Ruby can be used for a variety of purposes, including web development, desktop application development, system administration, and more. Some popular frameworks and libraries in Ruby include Ruby on Rails, Sinatra, and RSpec.

Important Points

• Ruby is an interpreted language, meaning it executes code directly, without compiling it first.
• Ruby is an object-oriented language, which means everything in Ruby is an object.
• Ruby has a simple syntax and is easy to read and write.
• Ruby is dynamically-typed, meaning the type of a variable is determined at runtime.

Summary

Ruby is a simple and powerful programming language that is easy to learn and use. It is popular in web development, but can also be used for a variety of other purposes. Understanding the basics of Ruby syntax and concepts is essential for anyone looking to get started with Ruby programming.
