Benchmark: JSON.stringify array vs join Updated

Script Preparation code:

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

Tests:

JSON.stringify
JSON.stringify(arr_small); JSON.stringify(arr_big);
