如何基於一個元素合並不同的數組對象

Question

如何合並這兩個 arrays？

array1 = [
  { image: 'image1', title: 'title1' },
  { image: 'image2', title: 'title2' },
  { image: 'image3', title: 'title3' },
];

array2 = [
  { downloadLink: 'downloadLink1', fileName: 'fileName1' },
  { downloadLink: 'downloadLink2', fileName: 'fileName2' },
  { downloadLink: 'downloadLink3', fileName: 'fileName3' },
];

我想得到以下結果：

array3 = [
  { image: 'image1', downloadLink: 'downloadLink1', fileName: 'fileName1' },
  { image: 'image2', downloadLink: 'downloadLink2', fileName: 'fileName2' },
  { image: 'image3', downloadLink: 'downloadLink3', fileName: 'fileName3' },
];

你可以簡單地試試這個：

 const array1 = [ { image: 'image1', title: 'title1' }, { image: 'image2', title: 'title2' }, { image: 'image3', title: 'title3' }, ]; const array2 = [ { downloadLink: 'downloadLink1', fileName: 'fileName1' }, { downloadLink: 'downloadLink2', fileName: 'fileName2' }, { downloadLink: 'downloadLink3', fileName: 'fileName3' }, ]; let result = [] array1.forEach(({image},index) => { result[index] = {image, ...array2[index]} }) console.log(result)
