Steps to build an e-commerce web application [closed]

I'm new to web application.

I'm planning to study full time (around 10 hours a day) in the next 6 months to learn to program, so I really need your help to make a wise plan for the next 6 months. I know basics of C++.

• However, as I'm learning using dev cpp I don't know what to learn next to build a real product

• I've read about something like API, Nodejs,React,XAMPP, ...but I don't really get what those concepts mean.

• I know some basic HTML to make a simple web page using notepad (just some words and pictures), but I don't know how to add some functions like interacting with the web, etc. (I mean the back end side)

Can anyone tell me what should I learn next and what frameworks (or tools) should I set up on my computer that I can code in (using Cpp or Java,etc) to build a database and then connect the e-commerce web with the database?

(My plan is to learn OOP, Data structures and Algorithms, learn some new programming language (like Java, C# and JS and SQL)(I don't know if it's the right path 🧐).)

Thank you 🙇🏼‍♀️ (and sorry for my inexperience).
