Local variables are one of the things CoffeeScript doesn't compile to modern JavaScript automatically: it uses `var` instead of `const` or `let`. Besides, using `$this = $(this)` is usually done to reference the current object in another function where the current object is a different one. Here we were using it with no clear purpose.
