Benchmark: Performance formatted phone number. Regex replace vs slice 2

Script Preparation code:

var value = '78005553535';
var regex = /(\d{1})(\d{3})(\d{3})(\d{2})(\d{2})/;
var mask = '+$1 ($2) $3-$4-$5';

Tests:

Slice
const countryCode = value.slice(0, 1); const regionCode = value.slice(1, 4); const partOne = value.slice(4, 7); const partTwo = value.slice(7, 9); const partThree = value.slice(9, 11); strOut = `+${countryCode} (${regionCode}) ${partOne}-${partTwo}-${partThree}`;
Replace
strOut = value.replace(regex, mask);
