- Makes development simpler. Programmers don’t need to worry about the intricacies of the underlying website — they can just start developing right away.
- Promotes cross-browser compatibility. jQuery is responsive to multiple platforms and resolutions.
- Increases engagement. jQuery includes features such as animations and effects, to create more engaging websites.
- Improves scalability. jQuery loads pages faster and consequently reduces the resources used when rendering a website.
What is jQuery?
However, just inserting jQuery into a website will do nothing. The developer will need to know how to call jQuery elements and how to access the jQuery library.
Let’s take a deeper look at what jQuery is used for.
What is jQuery Used For and Who Uses jQuery?
jQuery is primarily used by front-end developers. Uber, Udemy, and Twitter all use jQuery in their tech stacks. In fact, even websites that don’t still “use” jQuery for the foundations of their front-end may still include the library, because the library is integrated into many other plug-ins.
jQuery is best for:
- Full-stack developers who want to learn more about front-end programming.
- Aspiring front-end programmers who need a reliable library and framework.
How Do You Use or Install jQuery?
You can install jQuery through GIT BASH or PowerShell using a utility such as Visual Studio with the following command:
npm install jquery
Alternatively, you can download the jQuery script and include it in your website with the following code:
<script src = “[jquery location]”></script>
But because jQuery is a library, you will need to thoroughly read the documentation of jQuery to understand how it will be used to design a site. You can look at some jQuery examples if you want to learn more about what jQuery can be used for.
The Most Important Features of jQuery
Why is jQuery so popular and ubiquitous? Primarily because it offers an incredible array of functionality and makes that functionality easy for the developer to access.
The most important features of jQuery include:
- Effects and animations. This library makes it possible to, for instance, place shadows under text, or have text “swoop” in. jQuery can be used to create parallax displays for single-scrolling apps and complex gallery views.
- CSS manipulation. jQuery works alongside CSS and HTML5 to create a holistic platform that is easier to manage from an upper level.
More important, perhaps, is the fact that jQuery also has an assortment of plug-ins and a strong community backing.
If there are ever any issues in your jQuery scripts, you can always consult with the community. If you need code snippets, you can find them on Github or elsewhere. And there are many plug-ins that you can simply drop in.
And because jQuery is open source, it has been greatly improved on, streamlined, maintained, and managed by a large number of people throughout the years. Any potential issues, errors, or vulnerabilities are swiftly addressed.
jQuery vs. React: Is jQuery Still Relevant?
jQuery is used in more than 75% of the top websites in the world. While its usage is somewhat deprecated (most programmers refrain from starting an application with jQuery today), jQuery specialists and analysts are still extremely desired. This is because thereframe are many existing systems that still rely upon jQuery and that still need to be extended and maintained.
Nevertheless, when you look at recent trends, you can also see that React is rapidly growing in popularity. So, it’s usually a good idea for a developer to not only learn jQuery but also other frameworks and technologies.
jQuery and React aren’t mutually exclusive. Some applications do use jQuery alongside other alternatives like React, Angular JS, or Vue. But this isn’t usually advised because there’s a lot of overlap between systems.
jQuery vs. AngularJS vs. Vue
AngularJS is better for web application development, whereas jQuery is better for DOM manipulation. But DOM manipulation is largely deprecated today.
Similarly, Vue is seen as an easier-to-use option for web application development, with an intuitive framework and solid documentation. But jQuery is more well-known and accessible.
Are There Any Downsides to Using jQuery?
Why do some people consider jQuery deprecated? Many developers wouldn’t recommend starting a project with jQuery today. But that doesn’t mean that jQuery isn’t a good technology. There are simply a few major downsides to using it:
- jQuery is huge. Not only is it a massive library that grows over time, but because it isn’t compiled, the entire script is downloaded with the website. This can make websites slow, unwieldy, and difficult to scale.
- Parts of jQuery are now obsolete. This includes things like the jQuery DOM APIs. The jQuery DOM APIs that are used can make a site feel sluggish or slow to respond, thereby making a website less engaging.
These reasons (and others) are why people have been slowly moving away from jQuery development. But so many websites have already been designed with jQuery that jQuery is going to remain relevant for many years to come.
What is the Current jQuery Version?
At the time of writing, the most current jQuery version is 3.6.0, released on March 2, 2021. This included some bug fixes, compatibility issues, and a “slim” build that addresses some of the performance and size issues that are commonly complained about with jQuery. The “slim” build leaves out modules such as the Ajax and Effects modules, thereby creating a system that is smaller and more scalable.
There haven’t been many major changes to jQuery since it was first released — but the current jQuery version is extremely well-developed and stable. Although it may have its problems, jQuery has been modified, supported, and improved upon by a large and thriving community over many years.
How to Learn jQuery
Since jQuery is such an important, foundational language, many front-end and full-stack developers may want to learn it. According to ZipRecruiter, the average salary for a jQuery developer is close to $100,000 a year.
A few ways someone can learn jQuery include:
- Looking up information online. jQuery is very well-documented, so self-starters can begin learning it simply by installing it on their machine.
- Reading through jQuery tutorials. jQuery tutorials can be an excellent touchpoint for expanding your knowledge.
