Anyways, Magento store owners and developers must distinguish them clearly so that you can leverage each technique precisely and efficiently.
So, what are they?
To address this question, in this post, I will show you some insights into JS, JQuery, or Ajax, their relationships, and the fundamental features that distinguish them.
Besides, you can refer to a list of the best solutions integrated with these components to perfect your Magento 2 store.
Let’s dive in!
In other words, it is a client-side programming language. JS has a similar structure like C. In comparison with PHP, JS is different in language, but the same in order of operation.
JS lies in the third layer of the standard pie of web technologies, in which the other two are HTML and CSS.
The three technology layers are stacked appropriately.
Let’s consider a simple paragraph of text.
We can highlight the paragraph with HTML.
Then, add a few CSS texts to help increase aesthetics.

The differences between JS and other programming languages
|HTML||Short for “Hypertext Markup Language,” HTML is one of the most common programming languages on the web and builds the main blocks of a website. Examples of HTML tags are <p> for paragraphs and <img> for images.|
|CSS||CSS stands for “Cascading Style Sheets” which helps webmasters define styles and types of content. You can do it manually with every element in HTML.|
- JS requires no compiler because the web browser can compile JS with HTML;
- It’s easier to learn than other programming languages;
- Errors are more comfortable to spot and therefore easier to correct;
- It can be attached to certain web elements or events by mouse click;
- JS works on many browsers and platforms;
- Website interacts better with visitors;
- Faster and lighter than other programming languages.
Some of the shortcomings that can be mentioned are:
- Vulnerable to exploitation;
- Can be used to execute malicious code on users’ computers;
- Sometimes not supported in all browsers;
- Large code snippets;
- May be implemented differently depending on the device, resulting in heterogeneity.
As same as open-source software, jQuery acts as the JS library that simplifies the HTML client-side scripting. jQuery synthesizes all problems in JS into a library.
Suppose you want to select all elements having class-bss-li:
In case of jQuery:
It’s not too confusing, is it?
Pros of JQuery
Some critical features make jQuery so accessible and useful.
- Compact: jQuery is a fairly lightweight library – about 19KB (gzipped).
- Compatible with cross-platform: It automatically fixes errors and runs on all popular browsers such as Chrome, Firefox, Safari, MS Edge, IE, Android, and iOS.
- Easy-to-create Ajax: Thanks to the jQuery library, codes by Ajax can easily interact with the server and update content automatically without having to reload the page.
- Prompt processing of DOM operations: jQuery makes it easy to select DOM elements to traverse, and edit their content using the open-source Selector, which is also known as Sizzle.
- Simplify the creation of effects: Like the code snippet with animation effects, it overlays the lines of code, and you just need to add variables/content.
- Excellent support for HTML event methods: jQuery handles diverse events without messing up the HTML code with Event Handlers.
Cons of JQuery
Despite all those advantages, you should also note a few disadvantages, such as:
- Slow down the client: The client has to handle many functions created from jQuery. Excessive use of jQuery will make clients slower, especially for weak ones. Therefore, the developers must use an additional cache;
- Some functions may be missing: JQuery has a lot of functions, depending on the requirements on your site. But many functions haven’t been developed yet, so you may still need to use pure JS to build the missing features.
Moreover, it can be seen as a way to replace data using a server, and update web page sections without requiring to reload the entire page.
AJAX permits web pages’ content to be updated immediately when a user acts without reloading the page. As the action is done behind the scene, the user will not recognize the process of data exchange in the web pages.
Frankly, Ajax itself is not a single technology, but a term that describes the use of a combination of multiple technologies.
You can look at the comparison table between the regular model and the AJAX model to realize its overwhelming superiority.
Pros of Ajax
- Design a more diverse web and increase the interaction between the website and users;
- Utilize existing technologies, so it’s easy to learn and use;
- Its popularity has encouraged the development of molds that will help programmers avoid pre-collapsed traces;
- Supported in today’s popular browsers.
Cons of Ajax
- Don’t allow to be bookmarked in your browser favorites, since all processes occur in the background and aren’t visible in the address;
Nevertheless, the benefits Ajax brings to the digital technology platform outweigh the weaknesses. Therefore, Ajax is still favored by Magento developers in particular and other platform programmers in general.
#JQuery and AJAX
Even though both jQuery and AJAX simplify browsing experience, and all are popular these days, their functions and operations are distinguished.
While JQuery is a library to better client-side web page development, AJAX is a technique of doing XMLHttpRequest to the server from the web page and send/retrieve data used on a web page. AJAX can change data without reloading the web page.
In other words, it implements partial server requests.
- Library level (lib/web): Resources located here are available in any place within Magento.
- Module level (<module_dir>/view/<areaname>/web): If the module is enabled, resources added here are available in other modules and themes.
- Theme level, for a particular module (<theme_dir>/<VendorName>_<ModuleName>/web): Resources added here are available for [inheriting] themes.
- Theme level (<theme_dir>/web): Resources added here are available for inheriting themes.
jQuery in Magento 2
Typically, Magento leverages jQuery and jQuery UI libraries to simplify the creation of elements such as drop-down lists, buttons, accordions, and a lot more.
For more details, jQuery UI is a library extension offering a collection of brilliant widgets for projects. You can seek the full list here.
If you are planning to improve your Magento 2 store to be more attractive and seducing, then don’t ignore Magento 2 jQuery widgets. It’s a lot easier to use than pure JS.
