jQuery vs JavaScript
jQuery was created in 2006 by John Resig. It was designed to handle Browser Incompatibilities and to simplify HTML DOM Manipulation, Event Handling, Animations, and Ajax.
However, after JavaScript Version 5 (2009), most of the jQuery utilities can be solved with a few lines of standard JavaScript:
Set Text Content
Set the inner text of an HTML element:
jQuery
myElement.text("Hello Sweden!");
JavaScript
myElement.textContent = "Hello Sweden!";
Get Text Content
Get the inner text of an HTML element:
jQuery
myText = $("#02").text();
JavaScript
myText = document.getElementById("02").textContent;
Set HTML Content
Set the HTML content of an element:
jQuery
myElement.html("<p>Hello World</p>");
JavaScript
myElement.innerHTML = "<p>Hello World</p>";
Get HTML Content
Get the HTML content of an element:
jQuery
content = myElement.html();
JavaScript
content = myElement.innerHTML;
