Quick one that ended up being pretty much a pure Ruby tutorial, so I thought I'd cut out Rails entirely. Hope it helps!
And let me know if you'd like to see more tutorials for languages like Ruby or JS as a whole, as opposed to Rails specific videos.
Yes definitely would like to see more Ruby and JS code. All your content is awesome. Also switching between Ruby, JS and in my case Python becomes a challenge. I tend to forget the syntax.
Thank you very much, your yield explanation is the best that I found, I don't know why I did not get it befor but your explanation is really cool.
Great video for me, a beginner, very concise, very helpful
As always awesome pack of knowledge about ruby! Thanks a lot!
Great video. Thank you for explaining. Can you make a video series on rspec and factory bot please?
Amazing : )
This is awesome and it improved my understanding of these concepts. But when would you use a lambda vs a proc? They seem so similar.
When you need to control the argument that you pass, you should use lambda otherwise use proc.
Thank you for doing this,but in my opinion people already know the syntax if you want to be useful for beginners you should try to explain what is a block, lambda ect. The syntax of things can be Googled for 10 seconds no one needs to watch 12 minute videos for this.
Try to explain what does things do when to use one and not the other put short description of what they are and so on. Again thank you for even doing ruby tutorials in this case I just don't see what someone can learn from this video other than the syntax of something, but in this case they could also just Google it.
That's just my opinion of course, if I didn't know what a lambda is or block is this video would not have helped me understand that at the end.
