Script Preparation code:

var data = Array.from(Array(10000).keys());

Tests:

reduce
Object.entries(data).reduce((acc, [k, v]) => { acc[k] = v.toString(); return acc; }, {});
map + fromEntries
Object.fromEntries(Object.entries(data).map(([k, v]) => ([k, v.toString()])));
for loop
const dataObject = Object.entries(data) const acc = {} for (let i = 0; i < dataObject.length; i++) { const [k, v] = dataObject[i]; acc[k] = v.toString() }
