I am going through a minified js and reverse engineering to understand the behavior. Here is a function that I have no idea of what it does. Looking for some clues or hints to point me in the right direction.

 l = function (a, b, c) {
                return function () {
                    a[b]._.push([c, arguments])
                }

Here is a snippet where the function is invoked.

for (c = "post add".split(" "); a < c.length; a++)
        f[c[a]] = l(b, d, c[a]);
