Benchmark: Regex evaluation

Script Preparation code:

var matchDirective = /webapp-v-([a-z-]+)(?::([a-zA-Z_.-]+))?/,
    fullDirective = /webapp-v-([a-z-]+)(?::([a-zA-Z_-]+)(?:\.([a-zA-Z_-]+))?)?/,    
    attrName = "webapp-v-bind:class.ifdefined";

Tests:

Regex
var directivematch = matchDirective.exec(attrName), directivename = directivematch[1], directivopts = directivematch[2], pos = directivopts.indexOf("."), attrname = directivopts.substring(0, pos), buildIn = directivopts.substring(pos+1);
Substring
var directivematch = matchDirective.exec(attrName), pos = attrName.indexOf(":"), directivename = attrName.substring(0, pos), directivopts = attrName.substring(pos+1), posbuild = directivopts.indexOf("."), attrname = directivopts.substring(0, posbuild), buildIn = directivopts.substring(posbuild+1);
Full Regex
var directivematch = fullDirective.exec(attrName), directivename = directivematch[1], attrname = directivematch[2], buildIn = directivematch[3];
