Savvy.UI version 1.1.3 bring a numbers of new utility function to help you code, among added are Jrun.pickGrep, Jrun.inArrayGrep and Jrun.indexOfGrep. So one would ask, how are these functions can make my life easier? Let me gave you one example;

// this is how things got done in Savvy.UI before 1.1.3
var someFunction = function(method) {
    // assign value of method, if method=null then assign GET
    var method = Jrun.pick(method, "GET");

    // ensure method only POST or GET, default is GET
    method = (method.match(/^(get|post)$/i) ? method : "GET");
}

Using Grep you can actually do it this way;

var someFunction = function(method) {
   var method = Jrun.pickGrep(method, "GET", /^(get|post)$/i);
}
