[@xeonace]

Brad is a beast

[@Snoo29293]

Steven Griffith is a very good KZbinr too, he has videos about almost anything you could think of in JavaScript, web dev simplified does help a lot, but sadly there few stuff he hasn't covered about JavaScript in his videos, and sometimes he simplifies things a lot, which is good if you are struggling to understand something, but some concepts is good to know a little deeper. I recommend watching web dev simplified as an introduction to a topic, and then searching the concept deeper by watching some other videos, like the videos Steven Griffith makes, except if the concept is already simple enough and doesn't have much else to learn, like the array methods we were taught in this video, there do are some stuff he didn't talk about, about reduce method for example I believe it also can take a third parameter, but this video pretty much covered everything about these array methods.

[@jthomasaurus]

I watched a few videos of yours and was quickly convinced. I’m subscribed to your channel, your news letter, and checked out your “appearance” on the How to Code Well podcast. Really like your quick and to-the-point style of teaching, and you move quickly so I don’t get bored at all. I can always pause if I need to, but so many channels move too slowly. Thanks for all the help!

[@WebDevSimplified]

Thank you so much! I spend a lot of time trying to make sure my pace of explanation is a good mix of quick without being too fast. I generally live by the principle of explaining something really well once and then moving on since it is a video and not a live lecture you can always pause or rewind like you mentioned.

[@digitalkov]

You are the best! Concise, no bs, no nonsense. Please don't change. And please don't add any silly bs in parenthesis like (as this, or as that...)

I'm so glad you went in-depth with explaining reduce. I just started learning software dev 2 weeks ago and couldn't wrap my head around it.

[@SportsJames82]

Funny how much more helpfully and clear this is about these methods over some tutorials that spend 30 to 45 on each method

[@DavidWoodMusic]

My word thank you for showing this with multiple-property objects. Everyone does it with zero-property objects. You sir earned a sub 26 seconds into this video.

[@S0m0neRand0m]

Dang, if I had had the smarts of typing my problem into KZbin a couple hours earlier... you saved me dude! (just starting this JS journey)

[@Qrexx1]

Very useful summary! But keep in mind that with the forEach method you don't have the option to skip an element or to break the loop, in those cases you still need the 'for' loop or the 'for...of' loop so you can use the 'continue' or 'break' keywords.

[@roostercogburn3272]

This is (by far) the best explaination I've come across. I'm thinking that what probably makes array methods somewhat confusing in other explainations is that they usually introduce the concept of callbacks. It's much better to learn these ideas seperately. Before mentioning them as the array 'callback' methods.

[@calebprenger3928]

U can use reduce to consume an array of promises step by step await [1, 2, 3, 4].reduce(async (prevPromise, nextValue) => { await prevPromise; return new Promise((resolve, reject) => { setTimeout(() => { console.log('nextValue', nextValue) resolve() }, 200) }) }, Promise.resolve())

[@scheimong]

reduce() is seriously the best array method to know. It's useful whenever you want to generate a single value from the array's contents. Min, max, avg, std dev, whatever. The best part about it (and actually, all the other methods in this video) is that it turns the code from procedural to declarative. So instead of seeing a for loop, reading every line trying to understand what it's trying to do, a developer can simply read the first line, and whatever the code is trying to do is right there. The specific implementation is seldom important anyway. It makes the code so much cleaner and so much easier to maintain.

@@WebDevSimplified Was so good I watched it again :) Re .reduce() - that final zero - I was trying to think of a use case where you would have any other number than zero, but I couldn't! Any ideas?

[@WebDevSimplified]

@@najmantube the reduce function is used a lot to doing things other than just complex summing. For example it can be used to group an array of objects by a certain key which would mean the 0 would need to be an empty object {} instead. Also you may already have a subtotal that you then need to add in taxes and discounts so you would use the existing subtotal instead of a 0.
