Singleton:
The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance.

Example in ReactJS:

You might want to create a settings manager that's accessible from any component.

// SingletonSettings.js
let instance = null;

const SingletonSettings = () => {
  if (!instance) {
    instance = {
      theme: 'light',
      fontSize: '16px',
    };
  }
  return instance;
};

// Usage
const settings = SingletonSettings();
console.log(settings.theme); // Outputs 'light'

// In another component
const otherComponentSettings = SingletonSettings();
console.log(otherComponentSettings.fontSize); // Outputs '16px'
