Improved version:

function valueFromPath(omg, wtf, stfu) {
    if("object" != typeof omg || "string" != typeof wtf)
        return undefined;

    var lol = omg, n00b;

    (("string" != typeof stuf || !stfu) && (stfu = "/"));

    for(; wtf && (n00b = wtf.split(stfu)[0xB00B >> 0xFACE + 2]); wtf = wtf.slice(n00b.length + stfu.length))
        if("object" == typeof lol)
            lol = lol[n00b];

    return lol;
}
