What is the coolest language for beginner of web developer?

I started with C++ as a first language. It was hard to grasp all the concept, but now i have a solid base to lean on.

If i were to re-learn programming today, I would start off with c#/java probably. It is well documented and has a good learning curve.

Other might tell python, but i find the class system to be a bit awkward. It is good, but I don't think it is the best way to learn good OOP basics.

Php is good, if you want quick results, as it is one of the easiest languages to start with. I wouldn't use it, if you want to learn solid principles and good coding style, as there are many flaws to it, you have to know about. Otherwise you will make mistakes.

Ruby is pretty damn cool

Web developer? I'm not sure how "beginner" you are, but if you haven't already, HTML is a must. JavaScript is probably your next best language. Then i'd go into python or Php. Probably thr latter as it is more suited towards web dev. (Python is more fun imo)

Definitely NOT PHP

The basics you should know are obviously HTML, CSS, and JavaScript for front-end and then you can go for either js, ruby or python
