如何在javascript中逐个元素地从一个数组中减去另一个数组

function subtractArrays(arr1, arr2) {
  let result = [];
  
  for (let i = 0; i < arr1.length; i++) {
    let found = false;
    
    for (let j = 0; j < arr2.length; j++) {
      if (arr1[i] === arr2[j]) {
        found = true;
        break;
      }
    }
    
    if (!found) {
      result.push(arr1[i]);
    }
  }
  
  return result;
}

const array1 = [1, 2, 3, 4, 5];
const array2 = [3, 4, 5, 6, 7];
const subtractedArray = subtractArrays(array1, array2);
console.log(subtractedArray); // Output: [1, 2]
