给定数组，编写函数返回匹配项

function findMatches(arr, item) {
  const matches = [];
  
  for (let i = 0; i < arr.length; i++) {
    if (arr[i] === item) {
      matches.push(arr[i]);
    }
  }
  
  return matches;
}

const array = [1, 2, 3, 2, 4, 2, 5];
const item = 2;

const matches = findMatches(array, item);
console.log(matches); // [2, 2, 2]
