This course is a quick introduction to Ruby, one of the most useful and fun programming languages around.

There are plenty of programming languages around–but for many programmers, Ruby is special. Ruby originally came from Japan to take over the world of web applications, thanks to the popular Ruby on Rails framework. But Ruby isn’t just for the web: it’s a great all-purpose language, perfect to write scripts or process data. This short training, Ruby 3: The Big Picture, shows you what Ruby looks like, and what makes it unique. We’ll take a 10 miles high overview of the language, examining its strong and weak points. By looking at plenty of Ruby snippets, you’ll see why so many developers are in love with this weird and friendly language. After watching this course, you’ll know enough Ruby to answer one all-important question: is this language for me, and why should I learn it?

Reviews summary

Excellent ruby overview for beginners

According to students, this course is an excellent overview and ideal starting point for anyone new to Ruby or exploring the language. Learners frequently praise the instructor's clear and engaging style, which makes complex concepts accessible. The course effectively answers the question 'Is Ruby for me?' by covering core concepts like OOP, Ruby's unique 'magic', and its ecosystem. While many find it perfectly concise for initial exploration, some learners, particularly those with prior programming experience, noted a lack of hands-on code examples, finding it too theoretical at times for immediate practical application.
Ideal for those new to programming or new to Ruby specifically.
"Absolutely brilliant for a beginner!"
"As someone with no prior Ruby experience, this course helped me understand its fundamental concepts and object-oriented nature."
"Decent course for a complete beginner, but if you have prior programming experience, it might feel a bit too basic."
The instructor effectively clarifies complex ideas.
"The instructor does a fantastic job explaining core concepts like OOP in an easy-to-digest manner."
"Absolutely brilliant for a beginner! The instructor's style is clear and engaging. I loved how they demystified Ruby's 'magic'."
"The instructor made complex ideas accessible. I'm now keen to learn more."
Excellently serves as a high-level introduction to Ruby.
"This course is an excellent overview for anyone completely new to Ruby or considering learning it."
"It truly answers the question 'Is Ruby for me?' and makes you excited to explore further."
"This course is exactly what it claims to be: a great overview. It gives you enough information to decide if Ruby is for you without diving too deep."
Provides overview, but limited practical coding experience.
"I was hoping for a bit more code examples or practical applications, even for an intro. It felt a little too theoretical at times."
"Honestly, I found it a bit too high-level. I was looking for something that would immediately get me coding, even if basic."
"If you already know some programming, you might find it slow. It wasn't what I needed for getting hands-on."
