How to make AJAX call and in which component lifecycle methods should I make an AJAX call?

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      employees: [],
      error: null,
    };
  }

  componentDidMount() {
    fetch('https://api.example.com/items')
      .then((res) => res.json())
      .then(
        (result) => {
          this.setState({
            employees: result.employees,
          });
        },
        (error) => {
          this.setState({ error });
        },
      );
  }

  render() {
    const { error, employees } = this.state;
    if (error) {
      return <div>Error: {error.message}</div>;
    } else {
      return (
        <ul>
          {employees.map((employee) => (
            <li key={employee.name}>
              {employee.name}-{employee.experience}
            </li>
          ))}
        </ul>
      );
    }
  }
}
