Understanding web development is an ongoing process. To give you a foot up, I’ve gone all out to structure an all-encompassing, focused, AJAX course which I deliver to you in a way that will benefit you the most.

My course is distinguishable in teaching you "why" things work and not just "how" to do something mindlessly.


WHO IS MY AJAX COURSE FOR?

My course is for everybody, from beginner and advanced coders. You won’t need to do any other course after mine to know what AJAX is.

You only need to know a little HTML and JavaScript. If you hardly know JavaScript, it may be beneficial for you to first do my JavaScript course.

This course can be taken alone (you don’t need to do any other course) to achieve your goals.


WHAT IS AJAX?

AJAX allows you to update information on your web app dynamically, without a page refresh, and facilitates all-important streaming. A fine addition to your skill set. Smart and powerful.

For example. If a user wants to rate your product. You don't want the entire page to refresh when the user decides to give your product a star review, because of the unnecessary time it wastes, especially if your page is large.

Another example is a chat room. For obvious reasons, you don't want the page to refresh every time a new comment or a reply is posted.

AJAX goes further than just updating data on your page without a page refresh. With AJAX, you can also stream data. Think about watching a video before the entire video has downloaded to your machine. Think about Google Maps where you only need to download data that is relevant to you. AJAX makes this all possible.

Can you begin to see how powerful AJAX is, how essential it is today?


Knowing AJAX is crucial if you want to become a fullstack developer, as it will allow you to make server requests and listen for incoming data, asynchronously. It has been noted that AJAX can get tricky at times, and I don’t dispute this, but with correct training which includes explaining the fundamentals in a simple way, you will, like me, learn to master and love AJAX.

If you want to become a full stack web developer, you need to know about AJAX and that’s what this course is all about.


WHY IS THIS COURSE SO IMPORTANT?

  • Your favorite websites today almost certainly use AJAX

  • Other courses teach you about third-party libraries when using AJAX (like jQuery or Axios). This course will teach you how to use pure AJAX. No shortcuts. The real deal!

  • Making HTTP requests asynchronously is at the forefront of today’s web development. In fact, it is no longer advisable or the done thing to make HTTP requests synchronously

  • Knowing how to make a server request and listen for a response, fast, is a vital skill for any web developer to master

  • As a developer, you deal with data. This data can take many forms, but the most common is XML and JSON

  • You can use AJAX to transport HTML, images, JavaScript, XML, JSON and even plain text over the internet. My course covers all this

  • Using AJAX saves memory usage and speed up your site. For instance, Google Maps uses AJAX, so instead of loading the entire page for every event it loads the required section that you are looking at only. How efficient isn’t that

  • AJAX makes for better user experience, no argument in that

  • Every browser today has a built-in API (or object) called the XMLHttpRequest object, or the Fetch API. These objects give browsers the ability to communicate with servers, behind the scenes. This means a page can update (not totally upload) seamlessly without blocking anything on the user interface

After completing this AJAX course, you will certainly be knowledgeable, confident and able to manage or help others make AJAX requests.


LET ME SHARE MY AJAX KNOWLEDGE WITH YOU

Understanding how AJAX works will equip you to be an awesome fullstack programmer, relevant for today. Using AJAX effectively will allow you to update parts of your website dynamically without a page refresh, stream, and save you download time, save memory space and therefore ultimately improve user experience.

Take control through understanding and providing today’s users with the fast web experience they are coming to expect.

Mastering AJAX is challenging.

In this course, I take a deep-dive into explaining AJAX and how it works in a clear and simple way. Why do we need AJAX? Where did it come from? Why was the newer Fetch() API introduced? Why did we have to replace the XMLHttpRequest() object? Why do we have to use the new keyword when using the XHR object? What are Promises? What are Streams? What are the different data formats that we can transfer over the internet? By understanding (really understanding) these questions, and many more in the course, you will be able to easily build advanced websites and use the full stack process. You will be able to create dynamic sites that improve user engagement and experience.


WHERE IS AJAX USED

1. Form validation

It can be impractical and tedious to get validation results only after submitting a form. You can use AJAX in form validation, to give near instant real-time updates on validation.

2. Fetching data from a database dynamically without a page refresh 

If you need to fetch data from a database and display it to your page (like a blog comment, a chat response, or user's name), then using AJAX is a necessity.

3. Sort or Filter

If you need to fetch data from a database and display it to your page (like a blog comment, a chat response, or user's name), then using AJAX is a necessity.

4. Votes or Rating

The whole site need not to be refreshed if a user votes for something or rates your product. The voting and the displaying of the results can be done most efficiently using AJAX.

5. Chat websites

Chatting is always real time. That’s why AJAX is a must have if you are going to make a successful chatting panel in your website.

6. Blog Comments

You can load previous comments or can post a new blog comments with AJAX, easy peasy.

7. Captcha

To make captcha (reloading captcha basically) AJAX is also the best platform to use.

8. Streaming data & more

AJAX is used to consume data before its fully downloaded (saving you memory space and time), and a whole bunch more!

After experiencing my AJAX course, which I present in a fun way, you will be knowledgeable and confident.


WHAT THIS COURSE COVERS

This course is comprehensive, covering the essential fundamentals of AJAX.

AJAX refers to how browsers make HTTP requests to servers asynchronously, listen for results, and then do something with the data when it is received. AJAX is about speed and efficiency.

You can therefore think of AJAX as the engine that handles this entire back-and-forth process between the browser and the server.

Simple enough.

The only problem is that in order to truly understand AJAX, you need to understand many other concepts, and this is one of the unique aspects of my course and style of teaching.

Simple explanations and practical examples allow you to understand the following:


  • How to write AJAX the best way

  • What is asynchronous code and how does it differ from synchronous code

  • How to use AJAX to make asynchronous requests

  • What is the event loop in JavaScript

  • What is XML and how does it differ from JSON

  • How to parse an XML file using the DOMParser

  • What is the HTTP protocol and what is the HTTP/2 and HTTP/3 protocol

  • What are constructor functions

  • What is the XHR object

  • What is the new fetch() API

  • What are Promises

  • What are Streams

  • Why use Async/Await

  • URL Interface, Request Interface, Header Interface and a whole bunch more!

And yes, we will code real examples in a fun way, and look at how AJAX works (we use both the XMLHttpRequest object and the newer Fetch API).

Why should you learn so much about AJAX?

Because AJAX allows you to update certain parts of your webpage without a page refresh. It is used for streaming and more and today use of AJAX is essential on websites. It doesn't get better than that!


*** A comprehensive AJAX course on Udemy ***

Successful programmers know much more than memorizing a few lines of code.

They also know the fundamentals of how the browser & server interaction works behind the scenes which allows them to be fully creative, fix problems and enhance user experiences.

This is particularly true when it comes to AJAX.

If you’re wanting to become a full stack developer, you need to know, really know, how to make an AJAX request. You need to understand how AJAX was created, why the modern Fetch API was introduced, what Streams are, how Promises work and why the Async/Await keywords were introduced, and a bunch more!


A UNIQUE APPROACH

This course contains practical examples and fun challenges and quizzes.

Understanding how AJAX truly work is a vast topic. To get you up to speed, I’ve created a fun and comprehensive learning experience, embracing the content you need to know to succeed, and I deliver it to you in the best possible way to benefit you most.

And I make use of the latest and best features of JavaScript and browsers along the learning journey so you can stay ahead in your business.

You’ll learn simple, yet very powerful strategies to make server requests from a client.

By the end of this course, you'll be able to “speak” and “walk” AJAX by gaining an understanding of how you can build it and configure your request in practical ways. We dig deeper in every lecture, and this course has many bonus lectures which extend your knowledge base and test your skills with fun challenges.

This course offers you the best fundamentals and practical skills with AJAX. It can be taken alone (you don’t need to do any other course) to achieve your goals. You will emerge from this course with an advanced understanding and practical experience with making HTTP requests. It will take you to the point where you will understand what method (GET or POST) to use when sending data, how to define where the data goes, how to set up an AJAX engine and how to check for errors. This is awesome knowledge. This course will captivate you and catapult you to the next level and is an important part of your journey to become a leading Grandmaster in web development.

In this course you’ll learn everything about AJAX. From the basics of building an AJAX engine, all the way to learning about XML and JSON, asynchronous code, protocols, constructor functions, Promises, Streams, HTTP protocols, Fetch API, the Async/Await keywords, and various APIs such as Fetch, URL Interface, Headers Interface and Request Interface and a whole bunch more!

If you want to become a full stack web developer, you need this course!


HOW IS THIS COURSE DIFFERENT?

A unique feature of my course is the key detail I provide about how AJAX really works behind the scenes – a skill that every full-stack developer needs to master in order to utilize potential to improve.

I use simple and effective lessons to take you beyond starter libraries like Axios or jQuery. Libraries are helpful but are not a replacement for knowledge and once you can write your own, you will better be able to use and amend library code.

In this course, I focus on the more fundamental aspect of AJAX. I use plain JavaScript which is the core programming language you need in order to use AJAX. Once you master using JavaScript with AJAX, then integration of a library can benefit you and may make sense.

In order to understand how AJAX works, I dive into topics such as protocols, constructor functions, asynchronous code, data format types (JSON and XML), Promises, Streams, error handling and how to use the keywords Async/Await with the Fetch API.

Practice makes perfect

Theory is theory … but there’s nothing like getting behind your computer and typing in code. That’s why we will be coding, laughing and pulling out our hair together as we code real life websites and exercises during this course.

I love teaching and often use practical examples, which is why I start coding with you from the get-go. I will show you why the XHR object is a constructor function. I will show you the difference between JSON and XML. I will show you how to set up an XHR object, show you how to build Promises, show you what Streams are and how to use the new Fetch API. These concepts are all best learnt by coding up real examples. I can't wait.
