whats a static class code example

Example 1: what is static method

A static method belongs to the class rather than the object.
There is no need to create the object to call the static methods.
A static method can access and change the value of the static variable

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' ]
