// 1. Write a function called all which accepts an array and a callback and returns true if every value in the array returns true when passed as a parameter to the callback function.

const all = (inputArray, callback) => {
  return inputArray.every((input) => callback(input));
};

const allAreLessThanSeven = all([1, 2, 9], function (num) {
  return num < 7;
});
