How to remove object properties from objects in array using map() [duplicate]

Question

let objArr = [  { "name" : "Rohan", "request": true},   { "name" : "Sohan", "request": true, "modify" : "today", "expire": "tomorrow"},     { "name" : "Mohan", "request": true, "modify" : "today", "expire": "tomorrow"} ];

const newArr = objArr.map(v => ({ ...v, oldName: v.name, newName: v.name + '_copy', newRecord: true }))

console.log(newArr)

How to remove expire, modify, from the array?

Only oldName, newName, newRecord and request should display, the rest we can disable/remove.

Does this answer your question? How do I remove an object from an array with JavaScript? — 697

The simplest is to reverse the destructuring logic listing the props to remove explicitly and using rest parameters to keep the rest and avoid repeating all the properties you want to keepobjArr.map(({modify, expire, ...v} => ({...v, oldName: v.name, })); etc. — pilchard

Rather than deleting some attributes, you can copy only those properties which are required as shown below

const newArr = objArr.map(v => {oldName: v.name, newName: v.name, newRecord: true})
