Just playing around with ES6 Classes

es6-class.js

class Klass {
  constructor() {
    console.log('hello class!')
  }
  
  static util(a, b) {
    return a + b
  }
  
  render() {
    console.log('render')
  }
}

const klass = new Klass()
klass.render()

// can't call klass.util() as it is a static prop of Klass

const utilCall = Klass.util(1, 2)
console.log(utilCall)
