  • @nikitaalekseev991
    @nikitaalekseev991 3 роки тому +1

    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?

    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.

    Hi Max, I couldn't understand why you didn't use "this"keyword inside bind()

  • @maskman4821

    this reminds me of another question, what's the differences between appendChild() and innerHTML ? they both do the same things, aren't they ?

  • @9SMTM6
    @9SMTM6 4 роки тому

    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.

    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.

  • @follower90

    Especially I would think the bind approach is little slower than anonymous function (because of extra function call - bind).

    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?

    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)

    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!

    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.
