  1. Mistake in this line of the vanilla.js code?
    bar = foo + 10 // now bar becomes 25
    But thanks for an excellent article, especially with regard to summarising React’s shortcomings. Looking forward to seeing what Svelte can do over the next few years

  2. Thank you! Nice Article. Understood the point about using topology much better. Good addition to the presentation of Rich Harris. You state the following:

    “Wait, what? A compiler? Yes — a compiler. It’s such a bloody good idea that I don’t know why it wasn’t so obvious until now, and I’ll tell you why I think it’s so cool.”

    Exactly what I was thinking reading about Svelte. Relative new to the javascript world and surprised by the number of frameworks, tools etc. Very very complex, certainly for an old man having a C background. Of course, I love compilers! I love small footprints and software with good performance.

    Have fun with the computer and javascript.

  3. Thank you!
    But like the first commentor said, there is something wrong with your example and that point is the one that shows how Svelte is reactive:

    let foo = 10;
    $: bar = foo + 10; // bar is now 20
    console.log(bar); // 20 <==
    foo = 15;
    console.log(bar); // 20 <== bar is STILL 20

    Because this doesn't work, it's hard to see how they achieve reactiveness.

    Thanks
