const anyOrderArgs = ({ title = 'Title', body = 'Body' }) =>
  `Title: ${title}\nBody: ${body}`;

// Object shorthand
const filterKeys = ({ title, defaultValue = 'default' }) => ({
  title,
  defaultValue,
});

// Closures
const counter = (initialCount = 0) => {
  let count = initialCount;

  const increment = () => {
    count += 1;
  };

  return { count, increment };
};

// Array spreading
const duplicateArray = (array) => [...array];

// Async/Await
