Ruby syntax

Ruby’s syntax is based on a simple structure of statements, methods, and expressions. Here are some examples of Ruby syntax:

Declaring variables:

name = "Maria"
age = 25

Control structures:

if age >= 18
  puts "You are an adult"
else
  puts "You are a minor"
end

Loops:

for i in 1..10
  puts i
end

10.times do |i|
  puts i
end

Defining methods:

def sum(a, b)
  return a + b
end

result = sum(2, 3)
puts result

Working with arrays:

numbers = [1, 2, 3, 4, 5]
numbers.each do |number|
  puts number
end

Working with strings:

name = "Maria"
message = "Hello, #{name}!"
puts message

Working with classes:

class Person
  def initialize(name, age)
    @name = name
    @age = age
  end

  def introduce
    puts "My name is #{@name} and I am #{@age} years old"
  end
end

person = Person.new("Maria", 25)
person.introduce

These are just a few examples of Ruby syntax. The language also offers many other tools and features, such as metaprogramming, regular expressions, file handling, and much more.
