How can I implement data validation in Svelte?

You can implement data validation in Svelte by using reactive statements and form bindings. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

<script>
  let name = '';
  let error = '';

  function validate() {
    error = name ? '' : 'Name is required';
  }
</script>

<input type="text" bind:value={name} on:blur={validate} />
{#if error}
  <p>{error}</p>
{/if}

What if I want to validate multiple fields?

You can create a validation function that checks each field and updates the error messages accordingly. Would you like to see that?
