Convert array [ {''} ] to list [ '']

Question

I would like to convert array to a list like :

This :
[ RowDataPacket { id_name: '' } ]


To : 
[ '' ]

I just want a list, whitout name, no 'id_name'

This is a repeated question I think: https://stackoverflow.com/questions/31221980/how-to-access-a-rowdatapacket-object — Juljo Shahini, Dec 30 '22 at 08:45
Yes, it's a SQL array, but I want to convert it to do something after — Linda Daouadji, Dec 30 '22 at 08:45

Create a new empty array and when looping your rowDataPacket array, push them to new array.

Example;

// your array = rowDataPackets =[{id_name:''},{id_name:''},...]

const CleanArray = [];

rowDataPackets.forEach( ({ id_name : idName }) => { CleanArray.push(idName) });

console.log(CleanArray);

// CleanArray = ['','',...]

You can use Map Array method to iterate over this arr and get the key

const result = [ RowDataPacket { id_name: '' } ].map( item => item.id_name )
