In a parent component, such as TodoList, we have the following

import React from "react";
import ListItem from "./ListItem.js";

const TodoList = (props) => {
  return (
    <div>
      <ul>
        <ListItem content="item A"/>
        <ListItem content="item B"/>
      </ul>
    </div>
  );
}

export default TodoList;

And ListItem should look something like the following

import React from "react";

const ListItem = (props) => {
  return (
    <li>
      <input type="checkbox" />
      <span>{props.content}</span>
    </li>
  );
}

export default ListItem;

The crucial part here is that our return has a <span> that just directly renders the content prop we passed in!
