How to Modify Key Names in an Array of Objects (Renaming Keys)?

Modifying Key Names in an Array of Objects

Consider an array of objects:

<code class="javascript">var arrayObj = [
  { key1: 'value1', key2: 'value2' },
  { key1: 'value1', key2: 'value2' }
];</code>

To change all occurrences of "key1" to "stroke", utilize a combination of destructuring, rest, and spread syntax along with the map() function.

<code class="javascript">const newArrayOfObj = arrayObj.map(({ key1: stroke, ...rest }) =&gt; ({
  stroke,
  ...rest
}));</code>

This approach simultaneously destructures the object, renames "key1" to "stroke", and spreads the remaining properties into the new object.

The resulting newArrayOfObj would resemble:

<code class="javascript">[{ stroke: 'value1', key2: 'value2' }, { stroke: 'value1', key2: 'value2' }]</code>
