convert JS object to Object Array

问题

I have an array of objects as below:

[
  {
    Instance: 'USM 1',
    performance: '<DanPac_A>.<Daniel.DanOPCHub>.<A Session.Perfomance>',
    agc: '<DanPac_A>.<Daniel.DanOPCHub>.<A Session.AGC>',
    snr: '<DanPac_A>.<Daniel.DanOPCHub>.<A Session.SNR>',
    sos: '<DanPac_A>.<Daniel.DanOPCHub>.<A Session.SNR>',
    flowvel: '<DanPac_A>.<Daniel.DanOPCHub>.<A Session.SNR>',
  },
];

I need to take Instance out as a key and use its value as a property instead.

Expected output:

[
  {
    'USM 1': [
      {
        performance: 'value',
        agc: 'value',
        // ...
      },
    ],
  },
];

Any idea how to take it out?

你可以使用 Array::map() 方法:

const arr = [{
    "Instance": "USM 1",
    "performance": "&lt;DanPac_A&gt;.&lt;Daniel.DanOPCHub&gt;.&lt;A Session.Perfomance&gt;",
    "agc": "&lt;DanPac_A&gt;.&lt;Daniel.DanOPCHub&gt;.&lt;A Session.AGC&gt;",
    "snr": "&lt;DanPac_A&gt;.&lt;Daniel.DanOPCHub&gt;.&lt;A Session.SNR&gt;",
    "sos": "&lt;DanPac_A&gt;.&lt;Daniel.DanOPCHub&gt;.&lt;A Session.SNR&gt;",
    "flowvel": "&lt;DanPac_A&gt;.&lt;Daniel.DanOPCHub&gt;.&lt;A Session.SNR&gt;"
}];

const mapped = arr.map(({Instance, ...item}) => ({[Instance]: [item]}));

console.log(mapped);

You could use Array::map():

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const arr = [{
    &quot;Instance&quot;: &quot;USM 1&quot;,
    &quot;performance&quot;: &quot;&amp;lt;DanPac_A&amp;gt;.&amp;lt;Daniel.DanOPCHub&amp;gt;.&amp;lt;A Session.Perfomance&amp;gt;&quot;,
    &quot;agc&quot;: &quot;&amp;lt;DanPac_A&amp;gt;.&amp;lt;Daniel.DanOPCHub&amp;gt;.&amp;lt;A Session.AGC&amp;gt;&quot;,
    &quot;snr&quot;: &quot;&amp;lt;DanPac_A&amp;gt;.&amp;lt;Daniel.DanOPCHub&amp;gt;.&amp;lt;A Session.SNR&amp;gt;&quot;,
    &quot;sos&quot;: &quot;&amp;lt;DanPac_A&amp;gt;.&amp;lt;Daniel.DanOPCHub&amp;gt;.&amp;lt;A Session.SNR&amp;gt;&quot;,
    &quot;flowvel&quot;: &quot;&amp;lt;DanPac_A&amp;gt;.&amp;lt;Daniel.DanOPCHub&amp;gt;.&amp;lt;A Session.SNR&amp;gt;&quot;
}];

const mapped = arr.map(({Instance, ...item}) =&gt; ({[Instance]: [item]}));
    
console.log(mapped);

<!-- end snippet -->
