#### enableObjectSlots
使用 `enableObjectSlots` (文档下面会提到)。虽然在 JSX 中比较好使，但是会增加一些 `_isSlot` 的运行时条件判断，这会增加你的项目体积。即使你关闭了 `enableObjectSlots`，`v-slots` 还是可以使用

#### enableObjectSlots
Type: `boolean`
Default: `true`
Whether to enable `object slots` (mentioned below the document) syntax". It might be useful in JSX, but it will add a lot of `_isSlot` condition expressions which increases your bundle size. And `v-slots` is still available even if `enableObjectSlots` is turned off.
