11. Template Method Pattern:
The Template Method pattern defines the skeleton of an algorithm in the superclass but lets subclasses override specific steps of the algorithm without changing its structure.

Example in React:
Suppose you want to create a component in your React app with a template method for rendering a section.

import React, { Component } from 'react';

// Template Component
class TemplateComponent extends Component {
  renderSection() {
    throw new Error('Subclasses must implement renderSection()');
  }

  render() {
    return (
      <div>
        <h1>Header</h1>
        {this.renderSection()}
        <h1>Footer</h1>
      </div>
    );
  }
}

// Subclasses
class SubclassA extends TemplateComponent {
  renderSection() {
    return <p>Section A Content</p>;
  }
}

class SubclassB extends TemplateComponent {
  renderSection() {
    return <p>Section B Content</p>;
  }
}

// Component
const TemplateMethodPatternExample = () => {
  return (
    <div>
      <SubclassA />
      <SubclassB />
    </div>
  );
};

export default TemplateMethodPatternExample;
