.first() jQuery API Documentatio

This method does not accept any arguments. Given a jQuery object that represents a set of DOM elements, the .first () method constructs a new jQuery object from the first element in that set.

Use the :first-child selector to select more than one element (one for each parent).

To achieve the best performance when using :first to select elements, first select the elements using a pure CSS selector, then use .filter(:first) The first signature for the .find()method accepts a selector expression of the same type that we can pass to the $() function.
