How to Change Key Names in an Array of Objects Using JavaScript Manipulation?

Modifying Key Names in an Array of Objects

Changing key names in an array of objects requires some clever JavaScript manipulation. Let's dive into how you can achieve this:

In modern JavaScript, you can utilize destructuring with rest syntax, spread syntax, and array mapping to swap out specific key names in your array of objects.

Here's how it works:

<code class="javascript">const arrayOfObj = [{
  key1: 'value1',
  key2: 'value2'
}, {
  key1: 'value1',
  key2: 'value2'
}];

const newArrayOfObj = arrayOfObj.map(({
  key1: stroke,
  ...rest
}) => ({
  stroke,
  ...rest
}));

console.log(newArrayOfObj);</code>

In this example, we have an array of objects with "key1" and "key2" as property names. We map through each object, destructuring the "key1" property into a new variable named "stroke" using the rest operator to capture the remaining properties.

The result is a new array of objects where "key1" has been replaced with "stroke" while retaining the other properties.

This technique provides a concise and elegant way to modify key names in your array of objects, allowing for flexible and dynamic data manipulation.
