Benchmark: Testing regex vs split performance

Script Preparation code:

var file = "data:image/jpeg;base64,/9j/4QEKRXhpZgAASUkqAAgAAAAFAAABBAABAAigC5LMtzbXM6oFRkbEarsDDHOB24zVSztIUt0RYTKzPkEnBCAABAAigC5LMtzbXM6oFRkbEarsDDHOB24zVSztIUt0RYTKzPkEnBCAABAAigC5LMtzbXM6oFRkbEarsDDHOB24zVSztIUt0RYTKzPkEnBCAABAAigC5LMtzbXM6oFRkbEarsDDHOB24zVSztIUt0RYTKzPkEnBCf3jRRQB//2Q==";

Tests:

check regex
strOut = file.replace( /^data:(.*);base64,/, '' )
check split
strOut = file.split(',')[1]
