const TEST_OBJECT = {

  val1 : "hello",

  val2 : "world"

}



function getVal1(obj) {

  const {val1 : tempVal1 } = obj;

 // const tempVal1 = obj.val1 와 같음.. 

  return tempVal1;

}



getVal1(TEST_OBJECT);

const TEST_OBJECT = {

  obj1 : { val1 : "hello", val2 : "world"},

  obj2 : { val1 : "javascript", val2 : "es6"}

}



function getObj2Val1(obj) {

  const { obj2 : { val1 : tempVal1 } } = obj;

 // const tempObj2Val1 = obj.obj2.val1 와 같음.. 

  return tempObj2Val1;

}



getObj2Val1(TEST_OBJECT);
