I was recently wanting a refresher on Ruby, so perfect timing. Thanks for this!

[conmecha]

This is one of the few good videos I've come across that gives at least the basics of Ruby. The video will not make you a Ruby master, but it will at least give you enough knowledge to make simple projects in Ruby on Rails (or Ruby, it doesn't matter) or you'll be able to read 70% of the codebase of a project without confusion. Thanks for your efforts Mr. Rajat, I wish you the best.

@Rajat Talesra "Thank you, Rajat Talesra, for explaining Ruby in such a simple and easy-to-understand way! Your efforts to break down complex concepts make learning Ruby so much more approachable. Keep up the great work! 🙏✨ I’d love to hear more on advanced Ruby topics in future videos!"

[afzal_rahman]

Great effort, Rajat!
While many of the concepts were already familiar, your explanations were much simpler and more relatable. It was only after watching your video that I gained a clear understanding of topics like procs, lambdas, yield, and others.

Thank you once again for your effort in putting all this into a comprehensive 2-hour video.
