面试题与答案

The 'await' block in Svelte is used for asynchronous logic. It allows you to await a Promise and handle the resolved value or catch errors within the template.

Reactive declarations in Svelte create reactive variables based on dependencies, while reactive statements directly execute code when dependencies change. Declarations use '$:' syntax, and statements use '{# ... }'.

The '$:`` syntax in Svelte is used for two-way binding. It allows you to create a reactive variable that is both readable and writable within a component.

State can be shared between sibling components in Svelte by lifting the state to a common parent and passing it down as props to both siblings.
