ES6 Classes & Constructors

What structural design pattern does the MathUtils class demonstrate?

class MathUtils {
  static add(a, b) {
    return a + b;
  }
  
  static multiply(a, b) {
    return a * b;
  }
  
  constructor() {
    throw new Error('Utility class cannot be instantiated');
  }
}

Factory pattern
Utility class pattern
This demonstrates the utility class pattern: 1) Contains only static methods and no instance methods, 2) Prevents instantiation by throwing an error in the constructor, 3) Groups related utility functions under a namespace, 4) Provides better organization than floating global functions, 5) Follows the mathematical concept of a 'static class', 6) Similar to Java or C# utility classes like Math or Arrays.
Singleton pattern
Module pattern
