Hello guys I have a question that's confusing me. So I've been learning web development and I'm almost done with html, CSS and JavaScript. I'm interested in backend web development and would like to learn a language.

I would like to learn a language that's : beginner friendly , a language that would allow me to learn computer science basics like data structures and algorithms and also a language that's in demand. But the problem is I don't know which one to choose between the languages I listed .
This is the confusing thing :
JavaScript : if I go for JavaScript I wouldn't have to learn a new language all I have to do is learn node js , I can also use js for data structures and algorithms but my only problem is that I heard that there are not much jobs for nodejs backend developers.
php : I heard php is easy to pick up but it teaches you how to write bad code , I can't use it for data structures and algorithms . someone also told me that even though we have jobs for php developers the competition is too much as there are a lot of people doing php
python : I can learn data structures and algorithms with it , but I heard that the number of python developers are too much
Ruby : I heard it's easy to pick up but there are not a lot of jobs and they are also fewer Ruby programmers .

All this things I listed confuse me and I need help to choose a language , which would you guys suggest

web development in general is too competitive, you must offer something new on the table or forget it, I realised that hard fact, that is why I just went along with writing, can't waste my time learning something that I don't really like then coming out to kill myself on top of job wahala.

which language would you recommend?

I don't know, they are all popular and competitive, well, Just stick with javascript. But still note that they are competitive

Sting it with Python.

Forget competition.

Over to the gurus.
