Immutable Object Patterns with Object.freeze and Object.defineProperty

// Define an object with a non-writable property
const myObject = {};
Object.defineProperty(myObject, 'immutableProperty', {
  value: 'This property is immutable',
  writable: false, // Prevents the property from being overwritten
  configurable: false // Prevents the property from being redefined or deleted
});

// Freeze the entire object to prevent adding new properties
Object.freeze(myObject);
