  Write a function `count` that accepts an array and a callback as arguments. The
  function should return the number of elements of the array that return true when
  passed to the callback.
  
  Examples:
  
  let result1 = count([18, 5, 32, 7, 100], function (n) {
      return n % 2 === 0;
  });
  console.log(result1); // 3
  
  let result2 = count([17, 5, 31, 7, 100], function (n) {
      return n % 2 === 0;
  });
  console.log(result2); // 1
  
  let result3 = count(['follow', 'the', 'yellow', 'brick', 'road'], function (str) {
      return str.includes('o');
  });
  console.log(result3); // 3
  
  let result4 = count(['follow', 'the', 'yellow', 'brick', 'road'], function (str) {
      return str.includes('x');
  });
  console.log(result4); // 0
  */
  
  function count(array, cb) {
    let numTrue = 0;
    array.forEach((el) => {
      if (cb(el)) {
        numTrue++;
      }
    });
    return numTrue;
  }

  module.exports = count;
