What does $($(this)) mean?

Question

I saw some code around the web that uses the following statement

if ($($(this)).hasClass(\"footer_default\")) {
      $(\'#abc\')
        .appendTo($(this))

There is no meainig of doing that.

The following code return the same:

console.log($($(this)).hasClass("footer_default"))
console.log($(this).hasClass("footer_default"))

a boolean value depenging on if the selected element has or not the class footer_default:

.hasClass( className )Returns: Boolean
