1. AJAX vs. jQuery: What Are The Differences?
AJAX and jQuery are both tools that are extensively used in custom web development. Read the blog to
know the major differences and key aspects of these tools.
In today’s market, staying on top of the position with the latest tools and technologies is crucial for
every business whether it’s a startup or a large-scale enterprise. Well, there are plenty of tools used in
web and mobile app development. However, two popular tools that have strongly impacted custom
web development are AJAX & jQuery.
Both are primarily designed to help in making visually appealing, user-friendly, and stunning websites.
Though they’re used in conjunction, AJAX & jQuery have several differences. In this blog, we will
compare AJAX vs. jQuery and explore their different aspects. Let’s get started.
Definition of AJAX
AJAX or Asynchronous JavaScript & XML is a renowned web development technique that is extensively
used to create dynamic and interactive web applications. It uses JavaScript to develop an
XMLHttpRequest and allows the exchange of data with servers without refreshing or reloading the
whole page. AJAX offers a very responsive and seamless user experience but it can’t support standard
HTML. To use AJAX flawlessly, a proper scripting language is needed.
Features of AJAX
AJAX has a set of features and characteristics. Some of the best and most notable features include:
1. Asynchronous data exchange: AJAX enables data to be quickly sent & received from a server without
reloading the whole web page. This results in an excellent user experience and faster response time.

2. 2. Supports different data formats: While XML is one of the major parts of AJAX, it helps to manage
several data formats, including HTML, JSON (JavaScript Object Notation), plain text, etc. This makes AJAX
a versatile option for multiple use cases.
3. XMLHttpRequest object: AJAX mainly utilizes the XMLHttpRequest to facilitate data transfer. This
helps you make HTTP requests to the server & asynchronously manage the responses.
4. Cross-browser compatibility: AJAX supports modern web browsers. This makes it a reliable and
unique option for cross-browser compatibility.
5. Error handling: AJAX offers robust and efficient error-solving mechanisms. It allows developers to
gracefully manage network issues and resolve server errors.
Major Use Cases for AJAX
AJAX helps you freely communicate with the server. It has several use cases and applications. Some of
the major use cases include:
1. Form validation: AJAX is effectively used to validate the form on the client side before sending it to
the server. This offers real-time feedback to a user.
2. Notifications & live chat: Live chat, notifications, and other real-time communication features usually
depend on AJAX that help to send & receive messages by reloading or refreshing the page.
3. Auto-complete and auto-suggest: AJAX supports auto-complete and auto-suggest features, where
the server provides suggestions depending on user input without refreshing the entire page.
5. Data fetching from APIs: AJAX can also be used to fetch data from APIs. This makes it easier to
integrate several external solutions into web apps.

Key Benefits of AJAX
 Improves the interactivity between the visitors and the website
 Utilizes the latest technologies that are easy to employ
 Enhances overall user experience and faster response time
 Supported by several web browsers today
Definition of jQuery
jQuery refers to a concise, feature-rich & fast client-side JavaScript library that makes web development
processes simplified. As a scripting toolkit, jQuery helps to address inconsistencies & complexities in
JavaScript across browsers. Its primary objective is to minimize the lengthy javascript coding methods to
simple code lines. It also decreases the complexity levels of DOM calls & Ajax.

3. Features of JQuery
jQuery comes with a number of unique features and functionalities. Some of the best features include:
1. DOM manipulation: jQuery makes DOM manipulation simplified by offering a consistent & concise
API for choosing & modifying elements on the web page.
2. Cross-browser compatibility: One of the major objectives of jQuery is to reduce all browser
inconsistencies. This ensures that code consistently works across every browser.
3. Effects & animation: The jQuery tool includes built-in techniques for making animations & applying
different visual effects to elements on the web page.
4. Event Handling: In jQuery, the event handling feature is fully straightforward which makes it easier to
attach & respond to several user interactions like keyboard inputs, mouse events, clicks, etc.
5. Integration with AJAX: jQuery offers a smooth interface for developing AJAX requests that make the
process simplified in comparison to utilizing raw XMLHttpRequest.
Use Cases for JQuery
Just like AJAX, jQuery has a number of use cases & applications. Some of the major use cases include:
1. DOM Manipulation: jQuery is one of the best choices for choosing & manipulating DOM elements
that allows you to add, remove, and manage CSS & HTML attributes.
2. Cross-browser compatibility: One of the major benefits of jQuery is to manage all cross-browser
compatibility issues. This helps web app developers save a huge amount of time & effort.
3. AJAX Requests: Although you may utilize raw AJAX, jQuery’s AJAX technique can simplify the overall
process of developing asynchronous requests to the server.
4. Event Handling: jQuery simplifies handling events and user interactions effectively. This makes it a
perfect choice for making interactive web applications.
5. Effects & animation: If your web app needs visual effects & animations, jQuery will offer simple and
straightforward methods to implement them.
Major Benefits of jQuery
 A small library (19 kilobytes approx)
 Offers better assistance to HTML event techniques
 Helps developers avoid major browser errors
 Allows to write JavaScript easier & faster
 Compatible on different platforms including Firefox, Safari, Chrome, MS Edge, Internet Explorer,
etc.

When to Use AJAX?
In modern web application development, AJAX is used extensively. Technically, it can be used in the
following scenarios:
1. Fine-grained control: If anybody needs fine-grained control over the AJAX requests and responses.
Moreover, raw AJAX can also be a great choice, if anybody wants to work with a particular data format.
2. Less overhead: If you want to keep your JavaScript code lightweight, utilizing the raw AJAX may
minimize the necessity for entire libraries like jQuery.
3. Other library integration: AJAX can be helpful if a project involves other JavaScript libraries &
framework integration that can’t properly work with jQuery.

When to Use jQuery?

5. The main purpose of using jQuery is to make it simpler to use JavaScript on the website. This is mainly
used for:
1. Rapid development: When you would like to create web apps efficiently & quickly, extensive features
& concise syntax jQuery can significantly accelerate the speed of development.
2. Cross-browser compatibility: jQuery is a perfect option when cross-browser compatibility is a major
concern. It saves developers from creating complex browser-oriented codes.
3. DOM manipulation: If your task is based on selecting, animating, or managing DOM elements, jQuery
makes these tasks simplified and results in simpler codes.
4. Event handling: The event management system of jQuery offers a more organized and easier
approach when working with user interactions or complex event handling.
5. AJAX requests: While AJAX can be used to make asynchronous requests, the AJAX method of jQuery
is more convenient & straightforward.
Final Words
AJAX and jQuery both are in great demand as they have emerged as important tools for web developers
today. Although they make the browsing experience streamlined, their operations & roles are distinct.
While JQuery is used to enhance client-side web development, Ajax provides a mechanism to send &
receive data from web pages through XML Http Request and it can manage data without refreshing the
page. Technically, the ultimate choice between AJAX & jQuery depends on your project needs and
requirements. For more info, feel free to consult with our experts.
