Script Preparation code:

let data = [];

for (let i = 0; i < 1000; i++) {
	data.push(i);
}

let obj = data.reduce((acc, item) => ({ ...acc, id: item }), {});

let data = [];​for (let i = 0; i < 1000; i++) {    data.push(i);}​let obj = data.reduce((acc, item) => ({ ...acc, id: item }), {});​

Tests:

SPREAD ARRAY
let items = { ...data };
let items = { ...data };
LOOP ARRAY
let items = data.map((item) => item);
let items = data.map((item) => item);
SPREAD OBJECT
let items = { ...obj };
let items = { ...obj };
LOOP OBJECT
let items = Object.entries(obj).reduce((acc, [key, item]) => ({ ...acc, [key]: item }), {});
let items = Object.entries(obj).reduce((acc, [key, item]) => ({ ...acc, [key]: item }), {});
