javascript - Is it possible to write universal component? (react/typescript)

Is it possible to write universal component? which receives some object with similar data (for example: id, title, text, date) and renders it. But all objects have different keynames. Three objects for example, all of them have id, title, text, and date:

obj1 {id: 1, textVar: 'textString1', titleVar: 'titleString1', date1: '2000-10-10'}

obj2 {id: 2, title2: 'titleString2', someDate: '2001-11-11', otherTextVar: 'textString2'}

obj3 {id: 3, otherText3: 'textString3', otherDate: '2000-10-10', newsTitle: 'titleString3'}

Is it possible to write universal component, wich can work with any of objects?

interface UCompProps {
    id: number,
    title: string,
    text: string,
    date: string,
  }, 
}

const UComponent: React.FC<UCompProps> = (props) => {
  const { id, title, text, date } = props;
  return (
    <>
      <div>{id}</div>
      <div>{title}</div>
      <div>{text}</div>
      <div>{date}</div>
    </>
  )
}

export default UCompProps

Have no idea how to do it. Any advice how to do it?

If you know structures of all objects, then you can map array of that objects.

// in parent:
return (
  <div>
    {arrayOfobjects1
      .map(obj1=>({
        id:obj1.id, title:obj1.titleVar , text:obj1.textVar, date: obj1.date1
      }))
      .map(props=><Ucomponent key={props.id} {...props} />)
    }
  </div>
)

And also you can define that mapping functions for each types of objects:

// in parent:

const mapper1 = object1 => ({id:obj1.id, title:obj1.titleVar, text:obj1.textVar, date: obj1.date1});

return (
  <div>
    {arrayOfobjects1
      .map(mapper1)
      .map(props=><Ucomponent key={props.id} {...props} />)
    }
  </div>
)

Or you can render them all together after mapping of each array

const arrayToRender = [...arr1.map(mapper1), ...arr2.map(mapper2), ...arr3.map(mapper3)];
