hi, can i work on this issue?

kRaviteja7 commented 5 months ago

Try this it's working, This issue file is not presented in the project?

import { ref, defineComponent, SetupContext } from 'vue';

export default defineComponent( <T extends string | number>(props: { msg: T; list: T[] }, context: SetupContext) => { const count = ref(0); console.log(props, context),

return () => {
  return <div>{count.value}</div>;
};

}, { props: ['msg', 'list'], } );

不需要指定T类型，你可以看下这个函数类型定义。
