OMG! This post was amazing! After finishing the official Svelte tutorial, I can tell that you managed to cover many important topics with very few words!

Thanks! We need to start talking more about Svelte and the message behind the framework

Hello! Thanks for the great article!

If I understand correctly, there is a typo here.

I think that "Setting a prop is just like doing regular HTML." should be "Setting a prop is just like doing regular JS".

Hi, it's actually not a typo. What I meant was setting props in regular HTML <img alt="Nice image" src="nice-img.jpg"> (image tag with alt and src prop/attribute) is exactly the same in Svelte's template.

Thanks for creating this post! Reactive Statements remind me of the useEffect hook in React

Yes! But if you are using it to set derived states, you don't have to specify the dependencies manually.

Could you elaborate on setting props, in example 5? You export dark, so you can set it? But you set color, not dark. It's the one thing I don't understand

Thanks for asking, I see I should have made it more clear there.

So we are dealing with 2 components here, a simpler component CoolDiv.svelte (whose code is not shown), and the component we are looking at. Let's say it's called CoolDivWithText.svelte. All the code shown here belongs to CoolDivWithText.svelte.

The dark prop is on CoolDivWithText while color prop is on CoolDiv. CoolDivWithText wraps around CoolDiv; instead of offering arbitrary color options, we limit it to only allow dark theme or bright theme.

(I'm thinking of remaking this example)

Edit: I've updated the image in the article. Here is the original one this comment was talking about.

I'm just totally new to Svelte, but I really like this approach to crash-course.

Glad you liked it! I'm also working on a GraphQL crash course, which I will publish soon.

I updated the 5th pic, by the way. Hopefully, it's less confusing this time.

Sometimes we can become biased and miss the readers' point of view. It's hard to unlearn stuff. 😛 Thanks for pointing it out!

Its a hot topic lately but it doesnt bring anything significant to the table.

Speed, fully reactive state management, much smaller bundle size, write less code to do more? 😉

Yes. Thats what we already have with the popular frameworks.

Aside from that i appreciate you trying it out and letting us know what it can do.

Svelte has very good performance. If somebody wanted to make a hybrid app, this framework is a strong pick, as hybrid apps with popular frameworks often have visible performance issues.

Great write up. This should be considered the pre-tutorial. A nice 10,000ft view before diving into the nitty gritty.

Svelte is very appealing but what about meta data?
