ES11 - Static variables

Static keyword is used access the properties and functions directly wihout create an object

For example, class has a function which can be called using object(new operator of a class)

class Employee {
  getSalary() {
    console.log("Salary Details");
  }
}
const employe = new Employee();
employe.getSalary(); // Salary Details

if you try to access function with class name it throws TypeError {} is not a function

Employee.getSalary(); // TypeError: Employee.getSalary()  is not a function

using static keyword, we can directly calls function using class names

class Employee {
  static getDepartment() {
    return "HR"
  }
}
console.log(Employee.getDepartment());

static keyword also applies to functions.
