Benchmark: Regex extract info vs Split

Script Preparation code:

var stringList = ["Dev sprint 263" , "Dynatrace Sprint 263"];
var regexLessPerformant = /(?<version>\d{3})/;
var regexPerformant = /(?<version>\d{3})$/;

Tests:

regexLessPerformant
for(var i = 0; i < stringList.length; i++){ stringList[i].match(regexLessPerformant).groups.version; };
Coding with Javascript
for(var i = 0; i < stringList.length; i++){ var splittedBy = stringList[i].split(" "); splittedBy[splittedBy.length -1] };
regexPerformant
for(var i = 0; i < stringList.length; i++){ stringList[i].match(regexPerformant).groups.version; };
