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         


        

Answer 1

you can do it easily with ES2017

let {privateProperty1:exc1, privateProperty2:exc2, ...foo} = {
    x:0,
    y:0,
    divID:"xyz",
    privateProperty1: 'foo',
    privateProperty2: 'bar'
}

Here privateProperty1 and privateProperty2 are assigned to exc1 and exc2 accordingly. The remainings are assigned to foo newly created variable
