// You love coffee and want to know what beans you can afford to buy it.
// The first argument to your search function will be a number which represents your budget.
// The second argument will be an array of coffee bean prices.
// Your 'search' function should return the stores that sell coffee within your budget.
// The search function should return a string of prices for the coffees beans you can afford. The prices in this string
// are to be sorted in ascending order.
// ***********************************************************************************************************************

// solution 1:

function search(budget, prices) {
  const resultArr = [];

  prices.forEach(price => {
    if (price <= budget) resultArr.push(price);
  });

  return resultArr.sort((a, b) => a - b).join();
}

// solution 2:

const search = (budget, prices) =>
  prices
    .filter(price => price <= budget)
    .sort((a, b) => a - b)
    .join();

// to test:
search(14, [7, 3, 23, 9, 14, 20, 7]);
