What is the best way to get the key of key/value javascript object?

index.js

/** There are many roads, these are some of them... :) **/

const myObject = {name: 'Lujan', nickname: 'Lushan'}

for(let key in myObject){
  console.log(`Key: ${key}`);
  console.log(`Keys value ${myObject[key]}`);
}

//Or

Object.keys(myObject)
  .forEach(function eachKey(key) { 
    console.log(`Key: ${key}`);
    console.log(`Keys value ${myObject[key]}`);
  });
