Using an object directly inside JSX instead of JSON.stringify

Using an object directly inside JSX instead of converting it to a string with JSON.stringify() can lead to errors or unexpected behavior. JSX is designed to render elements, not raw JavaScript objects.

Common Mistake Example:

const data = { name: "John", age: 30 };

const MyComponent = () => {
  return (
    <div>
      {data}  // ❌ This will cause an error
    </div>
  );
};

export default MyComponent;

Error Message:

Warning: Objects are not valid as a React child (found: object with keys {name, age}).

✅ Correct Way Using JSON.stringify():

const data = { name: "John", age: 30 };

const MyComponent = () => {
  return (
    <div>
      {JSON.stringify(data)}  // ✅ This will render as a string
    </div>
  );
};

export default MyComponent;

Output:

{"name":"John","age":30}

✅ Better Approach – Render Object Properties:

Instead of just converting to a string, display the properties individually:

const data = { name: "John", age: 30 };

const MyComponent = () => {
  return (
    <div>
      <p>Name: {data.name}</p>
      <p>Age: {data.age}</p>
    </div>
  );
};

export default MyComponent;

Why This Happens:

React cannot render plain objects as part of the DOM. It expects strings, numbers, or React elements. This error is common when debugging data from APIs.
