Static

The static keyword defines the static methods or properties for a class. These methods and properties are called in the class itself.

class Car {
  constructor(name) {
    this.name = name;
  }
  static hello(x) {
    return "Hello " + x.name;
  }
}
let myCar = new Car("Toyota");

console.log(myCar.hello()); // This will throw an error
console.log(Car.hello(myCar));
// Result: Hello Toyota
