  useEffect(() => {
    fetchUser(userId).then(data => {
      setUser(data);
      setLoading(false);
    });
  }, [userId]);

  if (loading) return <div>Loading...</div>;

  return (

• Render only visible items
• Essential for large lists
• Available in all major frameworks

Memoisation:

// React memo
const MemoizedComponent = memo(function MyComponent(props) {
  return <div>{props.value}</div>;
});

// Vue computed
computed(() => {
  return expensiveOperation(this.value);
});

Testing Strategies

Framework-Specific Testing

React Testing:

import { render, screen } from '@testing-library/react';
import userEvent from '@testing-library/user-event';

test('counter increments', async () => {
  render(<Counter />);
  const button = screen.getByRole('button');
  await userEvent.click(button);
  expect(screen.getByText('1')).toBeInTheDocument();
});

Vue Testing:

import { mount } from '@vue/test-utils';

test('counter increments', async () => {
  const wrapper = mount(Counter);
  await wrapper.find('button').trigger('click');
  expect(wrapper.text()).toContain('1');
});

Choosing the right JavaScript framework is about finding the sweet spot between your team's capabilities, project requirements, and long-term maintainability. Each framework has its strengths and ideal use cases.

Start by clearly defining your project needs and team constraints, then evaluate frameworks based on real criteria rather than hype. The best framework is the one that helps you ship great products efficiently and maintain them effectively over time.

Remember: the framework you choose matters less than the quality of code you write and the user experience you deliver. Focus on building something valuable, and the technical choices will support rather than hinder your success.
