}

Tests:

Spread operator
function merged () { return { ...object, arr: null, } } for (let i = 0; i < 10000; i++) { console.log(merged()) }
Cloning
function merged () { const clone = JSON.parse(JSON.stringify(object)) delete clone.arr return clone } for (let i = 0; i < 10000; i++) { console.log(merged()) }
Object.assign()
function merged () { const changes = { arr: null } return Object.assign({}, object, changes); } for (let i = 0; i < 10000; i++) { console.log(merged()) }
