<textarea> 元素的行为类似于 Svelte 中的文本输入 - 使用 bind:value：
¥The <textarea> element behaves similarly to a text input in Svelte — use bind:value:
App
<textarea bind:value={value}></textarea>在名称匹配的情况下，我们也可以使用简写形式：
¥In cases like these, where the names match, we can also use a shorthand form:
App
<textarea bind:value></textarea>这适用于所有绑定，而不仅仅是 <textarea> 绑定。
¥This applies to all bindings, not just <textarea> bindings.
