In
beginning many web developers were confused about the term jQuery and
JavaScript. And they are aware to know what is actually difference
between jQuery and JavaScript. But they may surprise to know that
both are same. Generally jQuery is a set of JavaScript API, which is
designed to simplify HTML document traversing, animation, event
handling and Ajax interactions.
But
according to our choice to be a professional developer you must have
a solid command over JavaScript. If you are not aware about using
JavaScript for website development, check out Javascript MasterCourse. Once you aware about JavaScript Language, you might
analyze that jQuery Master Course fulfill most of your
requirements and it's requires less coding than conventional
JavaScript may require.
Introduction of
JavaScript
JavaScript is scripting language which is developed to
use within web browser. It is widely used for interface interactions.
Slides show and another interactive components can easily done using
this language.
JavaScript also widely used in creating game
development, web applications, server side programming etc. New
standards in JavaScript forces all web browsers to implement
JavaScript formally, which reduces developers time and frustration
trying to debug code for a specific web browsing client.
jQuery
Introduction:
In early days when jQuery was not developed, web
developer created their own frameworks in JavScript. These frameworks
allowed developers to work around some specific bugs without wasting
of time. Later a group of developers created JavaScript libraries,
which was open source and free of cost and generally called
JavaScript libraries.
So jQuery is a library of JavaScript developed by John
Resig. It is easy to use and extremely powerful in comparison to
other JavaScript libraries.
Which
one is better?
Developer spend lot of time debating whether jQuery or
JavaScript is best???? But the truth is that there is no correct
answer of this question.... Either can be selected for development
point of view, because whatever effects we perform using JavaScript,
that effects can achieve using jQuery.
Some web development projects require traditional
JavaScript, however jQuery is sufficient for most web development
projects. Although jQuery may be preferably a choice for experienced
developer, but as a fresher web developer should still take the time
to learn both JavaScript and jQuery.
One biggest difference between jQuery and JavaScript is
that jQuery has been optimized to support variety of browsers
automatically. But Unfortunately JavaScript still has some issues
with cross-browser compatibility due to poor JavaScript
implementation.
Example:
jQuery
$ (‘body’) .css (‘background’, ‘#ccc’);
JavaScript
Function changeBachground(color) {
document.body.style.background = color;
//or
document.bgColor = color;
}
window.onload= “changeBackground (‘red’)”;
A single line of code accomplishes same result in
jQuery, what it take 4 lines of JavaScript code.
