Hide certain values in output from JSON.stringify()

Question

Is it possible to exclude certain fields from being included in the json string?

Here is some pseudo code

var x = {
    x:0,
    y:0,
    divID:\"xyz

Here is my approach with the spread operator (...) :

const obj = { name:"hello", age:42, id:"3942" };
const objWithoutId = { ...o, id: undefined }

const jsonWithoutId = JSON.stringify({...o, id:undefined});
