This course is designed to provide learners with a practical foundation in Ruby programming, preparing them to write clean, maintainable, and efficient code for real-world use. Through a structured and hands-on curriculum, learners will explore Ruby’s capabilities for scripting, automation, and application development.

By the end of this course, learners will be able to:

• Understand and apply Ruby syntax, data types, and control structures.
• Build and organize programs using object-oriented principles such as classes, inheritance, and modules.
• Use blocks, procs, lambdas, and enumerables for expressive and functional programming.
• Write and debug command-line applications and automation scripts in Ruby.
• Perform file manipulation, regular expressions, and string operations using Ruby’s standard library.
• Handle exceptions and use built-in debugging tools effectively.
• Apply unit testing practices using RSpec and MiniTest frameworks.
• Follow Ruby style guides, naming conventions, and documentation standards.

Build real-world mini-projects such as a to-do app, calculator, and web scraper.Prepare for further learning in frameworks like Ruby on Rails for full-stack development.

Upon successful completion of the Ruby course, learners will receive a Certificate of Completion from Uplatz, validating their proficiency in Ruby programming fundamentals and development practices.

This certification proves your ability to build working Ruby programs, follow best practices in coding, and understand core object-oriented and scripting techniques. It serves as a valuable credential for entry-level development positions, freelance opportunities, or continued learning in Ruby-based frameworks.

By showcasing this certification on your resume, LinkedIn profile, or professional portfolio, you can stand out to employers looking for developers fluent in elegant, efficient scripting languages.

Ruby is a highly sought-after language in both startup environments and enterprise development due to its simplicity and productivity. Completing this course opens doors to roles such as:

• Ruby Developer
• Software Engineer
• Web Developer (Ruby/Rails)
• Scripting/Automation Engineer
• QA Engineer with Ruby Testing Tools
• DevOps/CI Automation Specialist
  
  

Ruby is widely used in web development, automation, test scripting, and back-end services. Major companies like Shopify, GitHub, Airbnb, and Basecamp use Ruby, making it a valuable skill for aspiring developers across tech sectors.

1. What is Ruby?
   Ruby is an open-source, object-oriented scripting language designed for simplicity and productivity, with a focus on readable syntax.

2. What are the key features of Ruby?
   Dynamic typing, garbage collection, mixins, metaprogramming, and a rich standard library are some of Ruby’s standout features.

3. What is a block in Ruby?
   A block is an anonymous piece of code that can be passed to methods and executed, often used in iteration and functional programming.

4. How is Ruby different from Python?
   Both are high-level and dynamic, but Ruby emphasizes convention, developer happiness, and metaprogramming more than Python.

5. What are mixins in Ruby?
   Mixins are modules that add functionality to classes without inheritance, promoting code reuse and composition.

6. What is RSpec?
   RSpec is a popular Ruby testing framework that supports behavior-driven development (BDD) and readable test syntax.

7. How do you handle exceptions in Ruby?
   Using begin-rescue-end blocks to catch and handle errors, optionally with ensure and else clauses.

8. What is a gem in Ruby?
   A gem is a packaged Ruby library or application that can be installed via RubyGems and reused across projects.

9. What are procs and lambdas in Ruby?
   They are objects representing blocks of code that can be stored in variables and passed as parameters, with slight differences in behavior.

10. Can Ruby be used for web development?
    Yes, especially with frameworks like Ruby on Rails, Sinatra, and Hanami, which simplify full-stack application development.
