jQuery vs. JavaScript's `this`: When Should I Use `$(this)` vs. `this`?

Understanding the Difference Between '$(this)' and 'this'

In the given jQuery tutorial, it is evident that $(this) is employed frequently over this. This begs the question: what differentiates these two syntaxes?

The distinction lies in the jQuery library's context. When working with jQuery, $(this) is used to designate an HTML element as a jQuery object. This enables access to jQuery-specific functions and methods, such as append(). Conversely, in the second example, reset() is a built-in JavaScript method directly available for forms.

To summarize, $(this) is employed whenever jQuery's functionality is required, allowing access to jQuery's extensive features. If a method is native to JavaScript, like reset(), it can be invoked directly without the need for $(this). This rule is exemplified by the following equivalence:

$(this)[0] === this

This implies that every jQuery element collection is an array where the first element contains the actual DOM element. Hence, for a unique result:

$("#myDiv")[0] === document.getElementById("myDiv")

Understanding this distinction is critical when working with jQuery, empowering developers to optimize their code and leverage the full potential of both native JavaScript and jQuery-specific functions.
