What Is jQuery?

jQuery is a JavaScript library that is fast, lightweight, and can do programing interactions you would normally use JavaScript for. jQuery is almost a simpified version of JavaScript, it takes common elements from JavaScript and does them with fewer lines of code.

jQuery hasn’t been around very long, it was release in January 2006, but has continually grown to become the most used JavaScript library used on today’s websites. This has been useful for coders doing mobile development and responsive design. The strongest element about jQuery is how compatible across all internet browsers, not required on version, release or operating system.

Why Use jQuery?

What is jQuery

The best features for jQuery is the what you can accomplish with less code than what it would take with JavaScript. The less code you need to write, the more time you save, the less the file size is, and easier to maintain and update.

The most common jQuery effects are hide and show, drag and drop, animations and form validation. By combining it with Ajax, another group of technologies to make our lives easier, you can make requests, updates and other queries to different types of databases

The Potential

What is jQuery

The greatest potential of jQuery is that it has hundreds of possibilities it already has, Then take those possibilities you can combine them with the previous possibilities to get more possiblities. Get the picture? You can dynamically change any element on your webpage dynamicly without any type of page refresh. You have probably seen a lot of these interactions and may not have noticed.

Here let me show you:

Amazon

Where To Get It

Download jQuery

jQuery is an open source library that you can download and start coding in a matter of minutes. The best place to download it from is their official site jQuery.com. By downloading it from here you know that you have the latest version.

There are two file versions to download, the compressed version or uncompressed. They compress the main library file down to save size, which increase download speed. This is the version you probably want as there is no need to "hack" the main file.

There is also a CDN option. This is where you pull the latest file version from their website. This way you know you always have the latest version and never need to worry about updating.

Take note: pulling a new version could also cause your code to break as objects, methods and function can change. This could cause your custom code to react differently.

Tutorials & Resources

Tutorials & Resources

Because of the high demand of jQuery there are hundreds of useful resources and tutorials available across the internet. A quick Google search or YouTube playlist and you will be over your head in information.

I have compiled a small list of some quick and easy resources for those you just need a place to start.

Just the Beginning

Mobile Development

jQuery is a new technology and is just the beginning. Developers have already taken this coding language to great heights and it will continue to improve on it. This is a coding language that would be worth sitting down and learning. If you have a strong understanding of JavaScript, jQuery will be easy to get a hold of.

More importantly a reason to learn it is for the growth of mobile development. As mobile continues to grow, there will be more of a demand for front end coders to know jQuery. As the time of this writing, most web development job opportunities will expect you to know jQuery.

Comment: 
JQuery is not a "new language branched from JavaScript", it's a Javascript code library. It's a library that creates a framework for simplified effects and interactivity in Javascript. A lot of the facts in this article about what jQuery accomplish's are true, but the underlying understanding of what jQuery is is totally misunderstood by the author.

I stand corrected
Comment: 
so jquery is only used for the lay-out of a website, right?
Comment: 
jQuery is used for interaction and usability. CSS usually controls the layout of the website.

jQuery is a library that makes it quicker and easier to build JavaScript webpages and web apps. Often with jQuery you can write a single line of code to achieve what would have taken 10-20 lines of regular JavaScript code

JavaScript offers a lot of things, but manipulating CSS or the HTML elements are not the only thing that JavaScript is intended to do. As such, it is a language where it does a lot more than manipulate the DOM, but that’s all that people normally equate it with. JQuery is much more focused just on the things that a web developer uses JavaScript for
Comment: 
Great stuff. I understand now as I know some javascript DOM and I am still learning, but this will help cut down some development time hopefully.
