best explanation I've ever seen on the web. This clears things up a lot. Thank you so much!!
The best explanation of 'bind' method in the world
Yeah bro, i did understand your exceptional taught, and it always got me! You're really good!
I've been looking for a good explanation about the bind and function execution for quite some time, and I found it today on my favorite youtube channel. Thanks, Max. =)
Thanks!
amzing!
That was perfect explain
I'm taking your JavaScript course, and indeed it is, bind () is really hard to understand.
I didn't get source code bro........😌
Your are great Max. Best explanation about bind so far 🔥🔥🔥
Have been searching for a practical explanation for bind for a long time. This one rocks. Subscribed!
Great explanation!
Maybe you should have mentioned the case when we don't use any arguments in bind and use an event.target inside function on which we called bind method?
ALWAYS great stuff, Max! You're very much appreciated!
Max, could you explain me, please. You used an anonymous function in an addEventListener like addEventListener('click', () => {calling another function}) - and to me it is a way clearly than using a method bind(). Particularly in case of referencing to 'this' object. In the lesson 8. Binding Class Method & Working with this of Chapter 10 - you implemented an expression addCartButton.addEventListener('click', this.addToCart.bind(this)); in the first time - I've learnt Java and Python.... but I don't remember subtleties like this one in those languages. My question is if both methods are completely interchangeable? Having watched your video I went to my code of the lesson and changed the line into addToCartButton.addEventListener('click', () => { this.addToCart() }); It works well as before. I don't see any differences so far. Thank you in advanced!
Max my question is why we need an event listerner?
I can modify the innerHtml with some like `Button Text`;
and avoid to add event listerner to browser right?
I buy your sveltejs course on udemy and it's very good!
I've will hate, love, hate and love Max for the rest of my life: the toughest but most brilliant teacher ever. Just a note when Max returns the function it might be even more clear by returning the whole content of the setAsActiveHandler like so
function setAsActiveHandler(goalId, event) {
console.log(event);
return function () {
const selectedGoal = goals.find(g => g.id === goalId);
activeGoalElement.textContent = selectedGoal.text;
}
}
this way at the first pass from the init() function setAsActiveHandler will be saved as a ready to be executed function at the click event by the user.
Very clear explanation! Whenever I need to refresh my memory, I always first check out your channel)
That was literally on point on what i was searching for, Are you sent by GOD??
Could I understand why is there a preference for arrow functions over bind?
Nice explanation, i just follow the patern before, now i know the reason
It would be awesome to have a video abkut the same but in React, I have tried to do it but with no much luck when it comew to understand it
Thankyou Sir, for to the point explanation.
Thanks, Max. Very helpful
Thank you, this is excellent and easy to understand 👍
Finally, bind() got bound to my mind. Thanks a lot, Max!
Tell something about core JavaScript.. Dom.. expanding collapsible table row.. hasownproperty.. for .. foreach.. map.. filter.. search... Fetch.. post.. splice.. etc..
Thanks 😊

Loving your Flutter course on Udemy right now!

Max, you are the best teacher in the game ♠️

Dude... get some sleep.
I'm ok, thank you ;)
excellent explaination!
Thank you Max! 🙂
That's awesome
Congratz Max. It was an amazing lecture!!
Thank you! 😃
Max is a star.
Seriously... I haven't had listened to any tutor so far that can explain things this well. No wonder people call him web-guru. This video is all I needed to understand this concept.
Hi Max, I couldn't understand why you didn't use "this"keyword inside bind()
this reminds me of another question, what's the differences between appendChild() and innerHTML ? they both do the same things, aren't they ?
With typescript last I checked bind did unfortunately not have the best of typing, add to that the need to provide a this context and I pretty much always use new defined (arrow) functions.
Yesterday I finally understood why we need bind() and today I successfully used it for the first time myself with complete understanding what is going on. Thank you Max. You are a JS ninja
Holy man! What a great explanation is such simple terms. I've read a few snippets on this topic and haven't found anything even close. This covers the "why" and "when" to use. Thnaks for sharing.
Especially I would think the bind approach is little slower than anonymous function (because of extra function call - bind).
Amazing tutorial Max!! Thanks 💙🙂
Why the automatic subtitles are for dutch language? :0
Nicely explained! Just a question! Can we just pass the goal object directly as an arg in setAsActiveHandler instead of its id, avoiding the find loop? Or there is a downside?
TIL
Awesome, thanks for the clarification !
Can I assume that the main purpose of anonymous function is to be a pointer to another function ? Or is it just one of their uses ? (Not sure if I made myself clear)
Thanks a lot for this explanation.. Just great!
Super! This is better than my work around.
Thanks you so much max...love from India
You, sir, deserve a lot more than you currently have.
Max, you are awesome. thanks for the idea and avoiding undefined problems when we call the function inside another function.
Max, thank you so much for sharing this.
this was amazing. how can your brain hold so much information?
Thank you for this awesome explanation 🏆
Very clear explanation. Thank you Maximilian
Amazing video! I finally understood the meaning of bind() and its usage
I unserstood it now better than the episode on udemy 😂
Hervorragend erklärt Max, danke dafür! Dein React-Kurs auf Udemy hat mich hier hin geleitet.
That is the first time I have understood the use of bind, thank you.
This was very helpful, thank you!
It seemed trivial at first, but then it got useful!
Nice explanation, thanks
Very helpful, thanks a lot!
I love your videos guys!
Max, I had just finished the .bind() section of your JS course and was still feeling a bit confused on when to use it. I spent a day or so reading through the MDN doc, but not making much headway. Suddenly today, I see this video, and your explanation here really helped to cement the concept in my head! Thank you!
Need to update that subscribe count on intro cut
Good point, we'll do so in the next weeks :)
Wasn t it possibile to store the función in a variable and pass that as a second argument?
@ChiKler true, i tried that on a piece of code I am writing and didn t work at all. Ibsolved that passing in an anonymous function as second argument
You are the most finely detailed instructor I know. Your lessons are never boring it's like you got some super power. Any chance you will ever do an updated laravel course? Php seems interesting and a good way of getting into the industry
Thank you so much! Never say never but at the moment I don't have such plans, sorry.
Thanks boss.
Gerade heute in meine Notizen mit aufgenommen: "bind() recherchieren" und schwups lieg ich abends auf der Couch und dein Upload kommt als Push-Nachricht 👍 Danke!
Das freut mich natürlich sehr :)
This is a great explanation of bind. Even though you only mentioned it in passing, it finally helped me understand the issue with "this" inside a function, why you would need "bind", and why arrow functions are so great.
Insted of bind we could use apply and it takes an array. Thank you!
