使用 Javascript 我如何将这个对象数组解构和重建为 json 对象

Question

Basically how do I convert this:

files = [
 { 
   transformation: 't_16x9_lg',
   width: 1920,
   height: 1080,
   bytes: 633634,
   format: 'jpg',
   url: 'xxx.png'
 },
 { 
   transformation: 't_16x9_md',
   width: 1440,
   height: 810,
   bytes: 383730,
   format: 'jpg',
    url: 'xxx.png'
 }
]

To this:

files = { 
  't_16x9_lg': { 
    width: 1920,
    height: 1080,
    bytes: 633634,
    format: 'jpg',
    url: 'xxx.png'
  },
  't_16x9_md': {
    width: 1440,
    height: 810,
    bytes: 383730,
    format: 'jpg',
    url: 'xxx.png'
  }
}

Stack overflow is asking me to add more details but not sure what else to add here. I guess just ask if you need more details.

Thanks.

Answer 1

You could destructure transformation and build new objects.

 var files = [{ transformation: 't_16x9_lg', width: 1920, height: 1080, bytes: 633634, format: 'jpg', url: 'xxx.png' }, { transformation: 't_16x9_md', width: 1440, height: 810, bytes: 383730, format: 'jpg', url: 'xxx.png' }], result = Object.fromEntries( files.map(({ transformation, ...object }) => [transformation, object]) ); console.log(result);

 .as-console-wrapper { max-height: 100% !important; top: 0; }
