Setup

var fastuid = () => ("00000" + (Math.random()*Math.pow(36,5) << 0).toString(36)).slice(-5);
    
    var fastuid2a = () =>fastuid()+fastuid()+fastuid()+fastuid()+fastuid()+fastuid()+fastuid()+fastuid();
    var fastuid2b = () =>Array.apply(null, Array(8)).map(String.prototype.valueOf,("00000" + (Math.random()*Math.pow(36,5) << 0).toString(36)).slice(-5));
    var fastuid3 = ()=>(1e40+'').replace(/[018]/g,a=>(a^Math.random()*16>>a/4).toString(16));
