Make JS even more difficult to understand.

compiled.js

(function (b, f, g, h, k, l, m, n, p, q, r, s, t, c, a, u, v, d, w, x, y, e, z,
    A) {
    h(f);
    c[d](g, [k, s, [m, n, p][a](y), r, [A, [[b, z][a](e), [q, v][a](e)][a](
        l)][a](w)][a](x));
    c[d](typeof document);
    b = new t(u);
    c[d](b)
})("param0", !0, "a", alert, "http:", "&", "www", "weibo", "com", "param1",
    "somewhere", "", RegExp, console, "join", "aaa", "data1", "log", "?", "/",
    ".", "=", "data0", "somefile");
