用習慣 python 之後, 覺得 c/java/javascript 不能回傳2個變數覺得麻煩, 在 javascript 可以用 array 或 dictionary 包起來傳, 收到後再解開.

//dictionary object sample:

function getNames() {
  // get names from the database or API
  let firstName = 'John',
      lastName  = 'Doe';

  return { firstName, lastName };
}

let names = getNames();

let firstName = names.firstName,
    lastName  = names.lastName;


// or by this way.
let { firstName, lastName } = getNames();
