Q: Object does not hook I am trying to learn hooks but have a problem with an object. Looks like useState doesn't treat my object as an object and I can't get hold of the second value.
function App() {
  const [fullName, setFullName] = useState({
    fName: "",
    lName: ""
  });

  function handleChange(event) {
    const { value, name } = event.target;

    setFullName((prevValue) => {
      if (name === "fName") {
        return {
          fName: value,
          lName: prevValue.lName
        };
      } else if (name === "lName") {
        return {
          fName: prevValue.fName,
          lname: value
        };
      }
    });
  }
  console.log(fullName.fName);
  console.log(fullName.lName);

 return (
    <div className="container">
      <h1>Hello {fullName.lName}</h1>
      <form>
        <input
          name="fName"
          onChange={handleChange}
          placeholder="First Name"
          value={fullName.fName}
        />
        <input
          name="lName"
          onChange={handleChange}
          placeholder="Last Name"
          value={fullName.lName}
        />
        <button>Submit</button>
      </form>
    </div>
  );
}

When I console.log the lName, "undefined" pops up, while fName works perfect.

A: In the else if (name === "lName") return statement you're returning a key named lname instead of lName.
