JavaScript How jQuery creates DOM elements jquery on dynamically created elements,dynamically created elements jquery event,

It is not a miracle, when you pass <div></div> to jQuery it matches it against the regular expression and tag check conditions like below

if ( selector.charAt(0) === "<" && selector.charAt( selector.length - 1 ) === ">" && selector.length >= 3 
 // Assume that strings that start and end with <> are HTML and skip the regex check
 match = [ null, selector, null ];
}

else matches it with below regular expressions to find out the element in the selector string.

    /^(?:\s*(<[\w\W]+>)[^>]*|#([\w-]*))$/

Once it find the element, then jQuery uses document.createElement("stripped Tag from selector") and will return the element with necessary jQuery methods added.

I would say until and unless you need it for your requirement, use document.createElement('div') instead of $('<div></div>').
