Rodrigo Pombo: [0:01] Svelte uses a custom file format similar to HTML. You can use curly braces to render data. Every Svelte file is a different component. You can add imports inside the script tag. To share the data with children components, you can create props using this port keyword.

[0:22] Inside curly braces, you can put any JavaScript expression. With the on directive, you can listen to events. Here, when the goalCount changes after a click, Svelte will re-render the component. You can also use a custom event to share data with the parent and use the on directive again to handle it and do something with the data.

[0:46] If you want to render a list, you can use the each block. Svelte also supports style tags. Here, the style only applies to the div from the current component and not the others.
