    import {tryit} from "@sveu/shared"

    function add(a, b) {
        return a + b
    }

    const add_async = tryit(add)
    
    const {result, error} = await add_async(1, 2)
</script>
<script>
    import {tryit} from "@sveu/shared"

    function add(a, b) {
        return a + b
    }

Example

        return a + b
    }

    const add_async = tryit(add)

    async function run() {
        const data = await add_async(1, 2)
        result = data?.result ?? undefined
        error = data.error?.message
    }

    run()
</script>

{#if result}{result}{/if}
