get_own_prop.js

let obj = {
  key1: "value1",
  key2: "value2",
  key3: "value3"
}

// convinient forEach
Object.getOwnPropertyNames(obj).forEach(key => {
  let value = obj[key];
  //use key and value here
});

// traditional for loop
let props = Object.getOwnPropertyNames(obj);
for(let i = 0; i<props.length;i++){
   let value = obj[props[i]];
}
