Benchmark: JS Split VS RegExp

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

/*your preparation JavaScript code goes here
To execute async code during the script preparation, wrap it as function globalMeasureThatScriptPrepareFunction, example:*/
async function globalMeasureThatScriptPrepareFunction() {
    // This function is optional, feel free to remove it.
    // await someThing();
}

Tests:

Split
/*When writing async/deferred tests, use `deferred.resolve()` to mark test as done*/ const hasSubdomain = (hostname) => { return hostname.split('.').length > 2; }; hasSubdomain('pixel.barion.com');
RegExp
const hasSubdomain = (hostname) => { return /^[^.]+\.[^.]+\./.test(hostname); }; hasSubdomain('pixel.barion.com');
