What web technologies are suitable for the thesis?

Question

IT education

As a diploma, I decided to develop a client-server application that would teach a foreign language to anyone. An example is the wonderful Puzzle English server ( https://puzzle-english.com/ ).
What technologies are best used to create such web services? It must store the information of each user, his actions - viewing the lesson, replenishing the dictionary, completing tasks. All this requires an unmeasured memory! How to store user sessions? What modern technologies allow this process to be accelerated? It is also planned to work with audio and video materials, the use of subtitles.

Answer 1

PHP, Ajax, MySql, HTML, CSS - they will be enough. They have a strong community.

Answer 2

Try nodejs + related stack

Answer 3

What technologies are you generally familiar with?
On the client, of course, JS / html / css , you can take jQuery or any framework to JS, if you know it
. On the back, any PL will suit you, from php to C ++. I would take node.js , because you can sketch out the background very quickly and do not need to learn another PL.
As a database, anything is also suitable. I would, again, because of the simplicity and speed in writing code, take mongoDB.
Yes, shit like
that Start with the structure of the database, and only then move on to such particulars as sessions and subtitles
