Returns jquery objects as this instead of dom elements
// Rather than declare a jquery object for a "on" callback for "this", it does it automatically
// For example:
$("div").on("click", function(e)
{
let _this = $(this);
_this.html("foo").css("background-color", "red");
});
// Gets converted to this
$("div").on("click", function(e)
{
// this is now a jquery object bound to the element, rather than the dom element
this.html("foo").css("background-color", "red");
});
