title: {@const ...}
|
|
---
|
|
|
|
The `{@const ...}` tag defines a local constant.
|
|
|
|
```svelte
|
|
{#each boxes as box}
|
|
{@const area = box.width * box.height}
|
|
{box.width} * {box.height} = {area}
|
|
{/each}
|
|
```
|
|
|
|
`{@const}` is only allowed as an immediate child of a block — `{#if ...}`, `{#each ...}`, `{#snippet ...}` and so on — or a `<Component />`.
