Static Methods

Expert-Level Explanation

Static methods in JavaScript are tied to the class itself, not to instances of the class. They are often utility functions relevant to all instances of a class but can also be called without creating an instance.

Creative Explanation

Consider static methods as the tools available at a community centre. They are not owned by any individual but can be used by anyone associated with the community. In a class, these methods provide functionality not tied to any single object but to the class as a whole.

Practical Explanation with Code

class MathUtility {
    static sum(a, b) {
        return a + b;
    }
}

console.log(MathUtility.sum(5, 10)); // 15, called without creating an instance

Real-world Example

A static method is like a public library's book return service. It’s a service provided by the library itself, not tied to any particular library member. Any member can use the service, whether they have a library book at the time or not.
