You completed the basics, so I think it's time. Ajax isn't hard, you can learn it in a day and you need a couple of days to remember it. JSON and XML are used for server responses (APIs). JSON is the most popular, but you can still come across XML. But again, it isn't hard to learn it.

In my opinion, you should learn some backend languages first. If you want to learn PHP, you also need to check it's famous framework Laravel. Also there are some other high-demand backend framework like NodeJS, Ruby On Rails, and Django. If you ask when should you learn AJAX and JSON, when you want to create a complex web application with RESTful API.

When you learn a backend framework it's really easy for you to understand JSON and Ajax . You're going to encounter JSON when you learn about RESTful web services don't let the name scare you it's just a style of communication across the web you'll find it a lot of fun. And as far as Ajax it's simply a technique that people use for asynchronous requests to make your app more dynamic and real time .

After completing frontend and before moving to backend make yourself familiar with ajax and json. You can start using them while you are learning backend.

You should start learning right after the first time when you'll hear the word "request" . (So it's time to start :D ) Don't worry , it's very easy ! Good Luck !!!
