Script Preparation code:

var smallArray = Array.from({
    length: 10
}).map((_, i) => `test_val${i}`);
var bigArray = Array.from({
    length: 10000
}).map((_, i) => `test_val${i}`);

Tests:

Join
const s1 = smallArray.sort().join(',') const b1 = bigArray.sort().join(',')
Stringify
const s2 = JSON.stringify(smallArray.sort()) const b2 = JSON.stringify(bigArray.sort())
