Miracles! Succinct definitions instead of mind boggling confusion. A rare thing.

[@parvathisachin3313]

To be honest, I think this is the most underrated channel, your explanations are so clear for novice programmers like me when we get stuck on some concepts. I cant thank you enough!

[@doabledanny]

Thanks, really appreciate that Parvathi!

[@struth32]

This is awesome! Your explanations are so clear and easy to follow, thank you so much😊.

[@DullBlaze]

Had a terrible time understanding the methods for arrays and this has been the most helpful yet! Not only did you go over each method but exactly what they did with very clear examples. Thanks so much for making the video!

[@ighareeb6402]

please make more JavaScript tutorials like this. Found it great as a beginner. Going over all the theory and examples then when I go for a walk I can listen to your channel and let it sink in even more! Thanks!!

[@infoessay21]

Thank you! This was the clearest explanation so far. Please, post more videos about JS topics.

[@vinayj6293]

I have learnt n understand the basic work these methods of array thanks a lot your time n patience

[@ybocktor7781]

Thank you, really clear and efficient.

[@GaneshH]

Thanks, really great walkthrough.
I've always been a bit unsure about reduce() but if I understood correctly its when you want to loop through the array and have each of the values contribute to something bigger to represent the array, the video helped a lot.
I never realised the some() and every() function existed, I'll definitely make use of it to ditch Boolean flags and For Loops!

[@doabledanny]

Thanks Ganesh, glad you found it useful! Yeah, I think you're right about reduce - it's when you want to loop through and reduce the array down to one value that represents something from the array (like the max value or total)

[@jestaman3356]

Great video and easy to follow. You also have a very calming voice that's pleasing to listen to. Cheers!

very good tutorial.

[@abeshsarkar4083]

nice video indeed,
short and load of js cores

[@alexthewebdesigner1856]

@DoableDanny
at 7:43 I don't understand why you had to use the spread operator instead of just copying names into namesCopy? Is it because, technically, namesCopy would reference the same array in memory if you didn't do it the way that you did?
Great video, by the way!

[@GayanRamyaKumaragtk]

Good explanation and I appreciate your effort. Please share a video series about data structures and algorithms with javascript. 🥰🥰🥰

[@doabledanny]

Thanks Gayan. I might make some data structure & algo videos in the future. For now, you could check out my blog as I have quite a few articles on that subject: www.doabledanny.com/blog/

[@ShuangsArtLife]

Thanks for sharing!
What's the extension in VS code installed?
Such as the hint when you use the method of "join" the string.

[@doabledanny]

My JavaScript extensions are JavaScript (ES6) code snippets and ESLint

[@nicolaed440]

cool video but so annoying when the keyboard and mouse are heard louder than the voice, yes I know programmers like this mechanical keyboard but in the video is....

[@siddhanttripathi5224]

logic is nicely explained but naming variables sucks
