What are static methods in JavaScript?

What are static methods in JavaScript?

Static methods are functions that belong to a class rather than an instance of the class. They are called on the class itself.

Can you give me an example of a static method?

Sure! Here's a simple example:

class MathUtil {
    static add(a, b) {
        return a + b;
    }
}

console.log(MathUtil.add(5, 3)); // Outputs: 8

What is the difference between static methods and instance methods?

Instance methods operate on instances of a class and can access instance properties, while static methods do not.

When should I use static methods?

Use static methods when you need utility functions that don't rely on instance data, like helper functions.
