Ruby Blocks, Procs, and Lambdas 🦁🐅🐻

[@ahmedabdelaalweb]

I've tried to understand these terms for a long time, and every time I walked away feeling like I get it but I can't put my finger on what's missing. You helped me fully understand them and made it very easy to follow. Thank you very much! I'm truly grateful.

[@cjav_dev]

So happy to hear that!! Thanks for watching

[@willyhorizont8672]

I'm just learning ruby. Your explanation of block, proc, and lambda is very easy to understand. Thank You!

[@marcioiherrero]

Very good, now I understand perfectly how it works by passing a block as a parameter and how it works with parameter in block. The example of the each method illustrated this functionality well, I was wondering how each of the Array and Hash worked behind the scenes. Thank you!

[@idreesibrahim5642]

love you boy! great concept you shared. Thanks.

[@c_zeroyt2556]

I read so many articles and blogs about procs and lamdas but now I understand fully, thanks.

[@TheLastLogicalOne]

Thank you, very helpful.

[@allicernoch]

Just pulled up this video to learn about procs and was like "Hey, I know him!" We sat at a table together during lunch at RailsConf. Excited to watch more of your videos, this one was great!

[@cjav_dev]

Hey! Thanks for watching! Great meeting you at RailsConf. Looking forward to rubyconf already :)

[@Ralph_Schumacher]

Great explained, THANKS!

[@yashsanghavi5338]

I think this is best video on KZbin for understanding blocks, procs and lambdas

[@juliantoro8416]

Thanks for the explanation, you explain things very easily

[@cjav_dev]

Thanks for the kind words! Glad you liked it.

[@Andy_a7]

the best explanation of how you implement in Ruby the thing known as a "callback function" in JavaScript.

[@PervadingPower]

Thank you! It's useful and interesting!🖖

Awesome vid, bro! I'm The Odin Project student and your video helped me understand procs! Thank you, keep up the good work!

[@actrox1]

It's my first time using Ruby and the way you are explaining it, I see everything looks clear.

[@aarya9382]

At 14:30, proc did return the last statement, however, puts returns nil so that’s why the output was like that

[@tahamanna3600]

Great video, thanks!

[@ClaudineyPerbony]

[@cjav_dev]

I’ve got time on my side. Anyone can do it!

[@ladmanoj1435]

[@cjav_dev]

Thanks for watching and thanks for your generosity:)

[@YasserKavousi]

great, that was helpful!

[@adan9975]

Extra super mega cool block, lambda and proc common uses case. Thanks yo 💪🏻💪🏻💪🏻💪🏻

[@SCBiscuit13]

I think there is an issue here. When you are trying to pass a lambda to the 'each' method. The '&' symbol is converting the lambda into the proc on passing vars to the method.

[@aualdrich]

Great explanation! Long time rubyist but I've never used/properly understood procs and lambdas like I should have. This helped a lot. Thanks!

[@cjav_dev]

Awesome! Thanks for watching!

[@larrydanso1129]

Thanks for making this simple to understand

[@developerfoe]

masterpiece...

[@dencam]

Missing your Rails tutorials

[@oiojin831]

thanks for the video, how can you call each method with block ?? each(students) do ... dont your block has to be iside of the parenthesis?

[@emilianomazzaglia7300]

A little comment when you explain the return behavior of procs, procs returns from the context that it was call, so it will return the each execution :D Everything else was really good!

[@FaraazAhmad]

Bit out of context but are those 4 names related to DC/Marvel heroes by any chance? :)

[@cjav_dev]

Yep haha good catch

[@dencam]

This is metaprogramming, right?

[@cjav_dev]

I’ve got another episode about meta programming. This one is more about understanding blocks.

[@bradalza98]

Please make a video on self, it's very confusing.

[@TheFranciscomoral]

still trying to understand the last one :(

[@cjav_dev]

Lambdas?

[@TheFranciscomoral]

@@cjav_dev tks for answering ! No , the logic inside the block to return the values ordered by how much times they appear in the array

[@shashankkestwal4454]

Please tell me that Rails will not die in the next 5 years.
