How Can I Extract Specific Properties from an Object Array?

Extracting Specific Properties from Object Arrays

Developers often encounter scenarios where they need to extract only specific properties from an array of objects. Each object might contain numerous properties, and the task of isolating the desired ones can be tedious. This article explores various methods to address this challenge.

One approach is to utilize object destructuring along with shorthand property names. By using this technique, developers can create a new object containing only the desired properties:

<br>const dummyArray = [{ "att20": "att20", "att30": "att30", "att70": "att70", "att80": "att80"}, { "att20": "att20", "att30": "att30", "att70": "att70", "att80": "att80"}];</p>
<p>const result = dummyArray.map(({ att20, att30, att70, att80 }) => ({<br>  att20, <br>  att30, <br>  att70, <br>  att80<br>}));</p>
<p>console.log(result);<br>

This method provides a concise and efficient way to extract specific properties while preserving the original array. By incorporating object destructuring, developers can avoid explicit property deletion, which is a common but cumbersome approach.

By leveraging the power of object destructuring and shorthand property names, developers can effectively isolate the desired properties from an array of objects, simplifying their code and enhancing maintainability. This approach offers a highly practical and adaptable solution to a common data manipulation challenge.
