What is Ruby - Hands-On Activity

What is Ruby

📖 Scenario: Imagine you want to learn a programming language that is easy to read and write, just like talking to a friend. Ruby is one such language, popular for building websites and apps.

🎯 Goal: You will create a simple Ruby program that introduces Ruby by storing a description in a variable and then printing it out.

📋 What You'll Learn

Create a variable called ruby_description with the exact text: "Ruby is a simple and powerful programming language."

Create a variable called language_type with the exact text: "dynamic and object-oriented"

Use string interpolation to create a new variable called full_description that combines ruby_description and language_type in the sentence: "Ruby is a simple and powerful programming language. It is dynamic and object-oriented."

Print the full_description variable

💡 Why This Matters

🌍 Real World

Ruby is used to build websites, apps, and automate tasks because it is easy to read and write.

💼 Career

Knowing Ruby helps you work on web development jobs, especially with popular frameworks like Ruby on Rails.

1

Create the initial description variable

Create a variable called ruby_description and set it to the exact string "Ruby is a simple and powerful programming language."

Ruby

# Create a variable called ruby_description with the given text
# Your code here

Need a hint?

Use = to assign the string to the variable ruby_description.

2

Add a variable for language type

Create a variable called language_type and set it to the exact string "dynamic and object-oriented"

Ruby

ruby_description = "Ruby is a simple and powerful programming language."
# Create a variable called language_type with the given text
# Your code here

Need a hint?

Assign the string to the variable language_type using =.

3

Combine the descriptions using string interpolation

Create a variable called full_description that uses string interpolation to combine ruby_description and language_type into the sentence: "Ruby is a simple and powerful programming language. It is dynamic and object-oriented."

Ruby

ruby_description = "Ruby is a simple and powerful programming language."
language_type = "dynamic and object-oriented"
# Create full_description using string interpolation
# Your code here

Need a hint?

Use "#{variable}" inside a double-quoted string to insert variable values.

4

Print the full description

Write a puts statement to print the full_description variable

Ruby

ruby_description = "Ruby is a simple and powerful programming language."
language_type = "dynamic and object-oriented"
full_description = "#{ruby_description} It is #{language_type}."
# Print the full_description variable
# Your code here

Need a hint?

Use puts full_description to display the combined sentence.
