Benchmark: cycle vs regex - MeasureThat.net

Script Preparation code:

function is_only_eng_letters_and_digits(str) {
            for (let index = 0; index < str.length; index++) {
                const code = str.charCodeAt(index);
                if (!(code >= 65 && code <= 90) && !(code >= 97 && code <= 122) && !(code >= 48 && code <= 57)) {
                    return false;
                }
            }
            return true;
}
var eng_str = "qwerty123";
var rus_str = "qwertyФЫВА123";

Tests:

cycle eng_str
for (let index = 0; index < 100000; index++) { for (let i = 0; i < eng_str.length; i++) { const code = str.charCodeAt(i); if (!(code >= 65 && code <= 90) && !(code >= 97 && code <= 122) && !(code >= 48 && code <= 57)) { break; } } }
cycle rus_str
for (let index = 0; index < 100000; index++) { for (let i = 0; i < eng_str.length; i++) { const code = str.charCodeAt(i); if (!(code >= 65 && code <= 90) && !(code >= 97 && code <= 122) && !(code >= 48 && code <= 57)) { break; } } }
regex eng_str
for (let index = 0; index < 100000; index++) { /^[A-Z0-9]+$/i.test(eng_str); }
regex rus_str
for (let index = 0; index < 100000; index++) { /^[A-Z0-9]+$/i.test(rus_str); }
