Functional Programming for Beginners

Learn the ideas behind functional coding without getting bogged down in the jargon.

[tsooooooo]

Great talk - one small note - you mixed up virtual dom with shadow dom

[samkim]

Please do more of these!! I am looking into being a programmer at one point, currently majoring in Computer Science in college and what not. I find these really helpful!!. You go Colby!!

[SirRelith]

Wrong! it's 10, because we turned 5 into 7, remember?
Oh man. I laughed so hard at this.
I love it.

Thanks for going into the depth you did in regards to core ideas, how to approach thinking about code, and how that actually manifests into real words and numbers.
You said some real enlightening stuff here. I learned a lot!
Thanks again. I hope to see more!

[MakZor]

Happy to see that you are alive Colby!
Hope you like what you are doing now, I think we all miss you and your league videos but do what you want and keep it up man! :D

[diegogutierrez]

Just... thanks. Thanks for making such "complex" topic into something easy

[xgrommx]

Redux, Rx, React isn't FRP. You use a wrong notation

[XibalbaProgramming]

Thanks for the video Colby, i have been wanting to get into functional programming for a while and this video just got me started.
Glad you're back

[karthikd]

I like the way you focus more on application rather than theory.

[lestervargas]

I usually don't comment videos, but this is AWESOME. Great man, thanks for the lecture.

[deltagamma]

It seems like relations would have to be figured out before hand as opposed to a step by step programming?

[lolbajset]

interesting video! but what are the practical real world applications of this? and why would one want to use this over say OOP?

[FortyS]

So you mean functional programming means faster or slower experience in terms of PC specs?

[stevemitchell]

Thank you for explaining what you mean byu side effects i a function. I have heard other use that term without giving examples of what side effects are. That will help me write better functions.

[cezarzbughin]

does anyone know how functions are programmed? how do they know where to return when everything is done?

[samhughes]

Comment, I mentally filter out older clips on programming/tech, because things change fast. I really appreciated this, and I have the concern that folk share my mental filter. Many of the solid FP defenses, like from Scott Wlaschin, Bill Boyd, and SICP-dude-forget-his-name are all several years old. It's one thing to glorify a paradigm, but coworkers are often lost on this, so I know it's not because the problem went away.

I'd love to see more content from you! I'm literally only watching your video to train YouTube to give me more FP stuff -- and your video snapped back with a "Hey. Don't you objectify me like that! My content is good on its own!"

[linestopaper]

Glad to see you making videos again Colby!

[epiphoney]

Wow, thanks for all those resources at the end of your slides.

[LeandroSilva-imbs]

Thanks for sharing your video. I don't mean to challenge your knowledge, but viewers should note that your "pure" function example at 8:05 is not actually pure. Your 'squareAll' function breaks the purity rule by relying on an external method call ('square'). It breaks rule #2 from 6:39. In order to make it pure, you would pass in all it needed via arguments (i.e. 'function squareAll(items, squareFn)...').

With the double click example you suggest that an OOP implementation would be much more complicated, it would have been great to show an OOP example for contrast. :)

[MrRolnicek]

So all this simplification is done for the benefit of the programmer? Aka. how does optimization work in this type of programming?
