import { defineComponent } from "vue";

export default defineComponent({
    setup() {
        return () => (
            <div></div>
        )
    }
})

import { defineComponent } from "vue";

export default defineComponent(() => {
    return () => (
        <div></div>
    )
})

import { defineComponent, h, VNode } from "vue";

export default defineComponent({
  props: {
    msg: String
  },
  render():VNode {
    return h("div", {}, this.msg)
  }
})

使用defineComponent是对typescript 有更好的支持
