I don't understand why everyone can't explain this topic in the same way. Brilliant. Thank you very much!
His voice is commercial. Everybody buys it first. When voice is welcoming, with the right attitude, pace, bang-on content, psychological impact of close shot of what he is doing (not the entire screen area) and proper-concise-basic explanation would have and certainly had brought him above all the alternate explanations. That's my friend called an educator tapping the maximum.
@@erhanertem196 jeeze, someone has a crush
So much better than the CodeCademy explanation!
I just came here from CodeCademy too, and I totally agree!
It's true
it's also better than the FreeCodeCamp explanation !
lol, also coming from freecodeacademy
yeah
You know why this is great? Because instead of just telling someone what to write and blow their mind you actually explain HOW what you are explaining came to be and WHY you would need it. Not just write this and try to get this. That is the x factor when it comes to coding tutorials. Well done as usual Mosh, I hope that made sense.
you could also use:
set fullName(value) {
[this.firstName, this.lastName] = value.split(' ')
}
Good shit.
Although it's a good practice and neat trick, I think it's kind of showoff to write comments like this.
@@sunspear1813 How else was Anna supposed to share this helpful information? You can't say that commenting alternate methods that seem better is showing off, then teachers would always be showing off, everyone with superior knowledge would be "showing off". In fact, Mosh is showing off by posting these videos! HOW DARE HE!
@@noahpeltier YEAH then in this case the whole ES6 is show off, why should we use arrow functions!!!
SunSpear said that because Anna is a woman. If it was a man's comment, he wouldn't say that. Thanks Anna and sorry for that. Keep commenting and "showing off". You help a lot of people that way.
Mosh should teach every course, no fluff, straight to the point!
This video answered ALL my questions on getters & setters. Thanks so much!
Thank you for explaining this from first principles.
Starting with a simple object, giving scenarios for why you'd need to implement this, and going from there.
You're wonderful at explaining topics like these, bravo!
Very simply explained! Formerly I got lost when other people described the same topic. Thank you very much!
Glad you started this video with a reason why we need this👍
Amazing! I understood this better than others spanish channels. Thank you
thank you, my current courses' explanation of how this works and its' use case was super clumsy.
This made so much more sense, thank you for the video. Hope you are doing well.
I like so much your explanation about javascript. I always can understand properly
Simple and clean explanation, lovely!
Only explanation i could find out there that made sense to me! amazing, thank you
This help me a lot.
Thank u very much. I will share this with my telegram group. Thanks again, very helpful.
very clear explanation. Thank you.
I can't believe I was able to understand this in 6 minutes compared to 3 hours of lectures. Saved my life for the exam, thanks lol
Great explanation!!! All videos are really great explained! Great teacher skills!
Simple & clean. Loving it! Keep it up!
Awesome explanation! I was struggling a bit with this concept. Thanks!
Thank you so much for this clear explanation!
Thank you for the awesome explanation, John Smith!!
😂😂😂
Getters and Setters:
2:38-3:04, contextual use case
3:05-3:14, purpose/rule
3:14-5:37, how to prepare
Ohhhh, so that's the difference, I finally understood, thank you very much. 💕 Awesome explanation.
This is the kind of stuff I read before for the question "What's the difference/advantage of a getter over a simple method?", I don't know if it resolves the question because I didn't understood a thing:
-"Given that without a getter, all we can do is poll the attribute for its value, anything else would require a special method which we would have to invoke on the value. Not insurmountable, but will take some thought."
Reading that again made me forget what I saw in the video, I need to rewatch. 😂
Thank you for clear explanation.
very informative and straight to the point thank you so much !
Love your Christmas ad. Its epic.
thank you very much for this video. I couldn't understand this topic as I am learning at codeacademy. You managed to explain it in a simple logic way. So happy to come across you video
An excellent illustration of Getters/Setters in JavaScript. Thanks, Mosh
{2021-09-22}
perfectly explained, thank you!
thanks for explaining, finally understand setters
Hi Mosh,
The getter setter implementation in this video is different from the one in your course of OOP.
Can you please explain which one is better?
Great explanation! Thank you.
amazing explanation!! Thanks so much!
so helpful. very glad i came here
Fantastic brother thank you very much!
your explanations are top notch thanks dude
Thank you ! very clear explanation.
with in 5 minutes Mosh helped me to understand the topic 😀
This video really helped solidify the ideas after I spent hours on the codecademy “meal maker” project! Appetizers, mains, and desserts, oh my!
Oh thank god not just me. I eventually gave up and followed the video and my code still doesn't work. I've been loving the course so far but this was so weird.
Hi nice tutorial, but why can't we do the smae task whitout naming those functions get and set?
Great , professional way
Great explanation, thanks!
Quick and good explanation, thanks alot!
on spot! Thanks a lot for this Mosh!
For learning purposes I used Get to return a value of an outside variable but then I couldn't Set it.
Is there a way to do so ?
if I simply use :
get abcde( ) { return outsidevariable }
set abcde(valuenew) { outsidevariable = valuenew }
and then outside I type:
object.abcde = `whatever`
keeps returning the outsidevariable original value and not the `whatever` I tried to set.
Wow! That's well explained 👏🔥
Great explanation. Thank you so much. I have ticked the bell icon :)
Awesome video for beginners.
tried to find the next lecture's video and couldn't, can i get a link or the name of it? thanks!
Thank you Mosh! AMAZING explanation. Do you have courses on Udemy?
Hello Mosh thanks for this great tutorial on functions, please can you also make a video on how to use anonymous functions in JavaScript?
How is this related to classes? I know this concept from back in the days when I learned Java to access class attributes. Here I can also do it with objects and that's great, but how is this related to the new ES6 classes in JS?
Thank you!!! This is 1000x better than Treehouse's video on getters and setters. Their instructor they currently have is horrible. Plus it doesn't help when their sample code are using the same variable name that's confusing the heck out me. "get owner(){....} set owner(owner){this._owner = owner; ....}. What the heck is going on! Also thanks for going over pre es2015 code. I would like to know or at least recognized the previous format when I come across it.
Great video, thanks mosh
hi mosh you have an amazing style in explanation but please i need your data structure course in JavaScript
That's awesome, understood it fast because of your explanation. What theme are you using, btw?
bless u, please, never stop what u are doing, im picking this lifeskill and frankly, thanks alot
amazing explanation
What is this setup to get the output like that in VSC?
i really like this explanation - u earn my sub badman!
is this. refereing to the person object ? or to the fullName method ?
Awesome tutorial
You have no idea how long i tried to understand this
Insane explanation🌟
How do you test code in the chrome side by side?
Thank you so so much. Just...thanks man!!!
Please I have a question....
Why does the "this" keyword work when we put them into objects when initializing since objects cannot be accessed before initialisation?Is it because of hoisting,please just explain this to me...
Excellent. Ty alot
Can you send exercises to pratice this features?
What version of javascript for this video?
only half way in, but wow what an amazing explanation
Good explanation.
Can Getters and Setters be applied within Constructor functions of objects? I tried, but it's not accepting them in a Constructor. Please explain us if there's a way.
Thanks Hamadani!
Thank you!
nice explanation
Thanks man, couldn't understand the example from Eloquent JS chapter 6 but this is crystal clear. You're the best.
I couldn't understand anything from Eloquent JS lmao
Maybe. I think the examples were a little too complex for me in Eloquent JS. Anyway, your video was helpful! Thank you Mosh.
Hey iMpetus. Even though it's a complex book and sometimes you have to reach for other resources in order to fully comprehend things, I still 100% recommend it because once you get through it you'll have a solid understanding of the concepts.
Thanks for sharing your insight Nanika. I will give it another try. :)
@@programmingwithmosh sir, why you always use "const" rather than "var" or "let"...?
Hey Mosh, i'm wondering, why aren't you using the this keyword in the return of the setter property?
Thanks a lot man
Whoa, nice video, it was a great explanation 😄
Thank you sir
I just came back from CodeCademy to better understand getter and setter.
So getter is just to be able to call a method like a property ? Codecademy mentionned this is relate to privacy (with the convention _prop) . is it also linked ?
I am assuming that nothing protects firstName and lastName from being updated directly? There is no way to protect the name properties?
Thanks a lot
This guy is good at explaining
In setter without using the variable name const the split return an string
Why it happens?
so, what's about class static getter & setter?
Can we specify getter and setter to a constructor function ?
English subtitles: Mosh Hamedani ( Marsh comma daddy )
Does anyone know how to do this part
set fullName(value) {
const parts = value.split(" ");
this.firstName = parts[?];
this.lastName = parts[?]
}
if someone's first and/or last name is more than 1 word => so not parts[0] and parts[1]? Like for example "Juan García Reyes" where "García Reyes" is the last name, or "Anne Marie Smith" where Anne Marie is the first name.
this.firstName = parts.slice(0, parts.length - 1).join(" ");
_// slice from index 0 until before the last index_
this.lastName = parts.slice(1).join(" ");
_// slice from index 1 until the end of array_
_// join(" ") joins all elements into a string, each element separated by " "_
Thank you
I don't understand the setting new full name part. Why did it work with just person.fullName = 'John Smith' ? Shouldn't it be person.fullName( 'John Smith' ) ?
Thanks Mosh
Really god thank you!
Now it's clear to me :)
thanks for the video, do you also speak farsi ?
Finally i get it from this video
