es8Tests.js

// padStart and padEnd
var now = new Date();
console.log(`${now.getHours().toString().padStart(2,"0")}:${now.getMinutes().toString().padStart(2,"0")}`)
/* Output:
09:41 (or something simular)
*/

// Object.values
var objectTypes = {}
Object.values(window).map(obj => {
  const type = typeof obj;
  if (typeof objectTypes[type] != 'undefined') {
     objectTypes[type] = objectTypes[type]+1;
  } else {
    objectTypes[type]=0;
  }
})
var output = `The values of the keys found in the window object of the page "${document.location}" has:`
Object.keys(objectTypes).map(type => {
  output+=`\n"${type}" found ${objectTypes[type]} times`
})
console.log(output)

/* OUTPUT:
