UPD. Outdated a little bit.Basically, Ajax (Asynchronous Javascript and XML) is a set of technologies that allow a website to send requests to a web server asynchronously. This means a Website doesn’t have to be fully reloaded to retrieve or send information to the webserver, this allows for much smoother interactions. All the popular services out there use it in some way or the other. Applications like Facebook, Twitter, Instagram, Gmail, Google Maps, Spotify, etc cannot function without AJAX.https://code.djangoproject.com/wiki/AJAX https://data-flair.training/blogs/ajax-in-django/ https://www.careerride.com/Ajax-Overview-Advantages-Disadvantages.aspxLinkedin Feel free to contact me.
