Hello free coders!
I want to set up a web page for personal purpose (non-profit) similar to wallapop functionality but without money transactions.
I am an experienced embedded programmer but I have no idea about front-end nor back-end web development.
For that reason, I need to learn some topics before starting my project.
Which languages and topics do I need to learn to build my web page? As I said it would be similar to wallapop but without money transactions. I would like to use free languages and frameworks because it is a non-profit project and I do not want to pay any royalties.
