cannot access static methods in a class js code example

Example 1: js class static

class ClassWithStaticMethod {
  static staticMethod() {
    return 'static method has been called.';
  }
}

console.log(ClassWithStaticMethod.staticMethod());
// expected output: "static method has been called."

Example 2: get static methods of class javascript

class Hi {
	constructor() {
      console.log("hi");
    }
   	my_method(){}
  	static my_static_method() {}
}

function getStaticMethods(cl) {
  return Object.getOwnPropertyNames(cl)
}

console.log(getStaticMethods(Hi))
// => [ 'length', 'prototype', 'my_static_method', 'name' ]
