What is the best language for web programming?

Question

I programming web aplication with Django framework, but it seems ruby on rails is easy and fast. many people use php or java

Answer 1

HTML, CSS, JS are the one that are required...
You can make websites without the frameworks above and PHP...

Answer 2

Depends on whether you want to go front-end(only design webpage), back-end (only design server side stuff), or go full stack(back-end and front-end). In any case, HTML and CSS are the basic must-have languages so definitely learn those pretty well. For all other purposes, you could use JavaScript. It has a framework for almost anything. You could use Ruby, PHP or any other language/framework too.
At the end of the day, the language or framework you choose doesn't matter as much as your ability to solve problems. So pick the one you love and are the most comfortable with☺
I'm still learning advanced HTML5 and CSS3 and like JavaScript. But I will still try other languages too. If you want to learn full web development, I highly recommend https://www.freecodecamp.com/
They teach really advanced stuff fairly easily. I went from making webpages with simple headings and paragraphs to buttons with bootstrap and importing fonts from Google APIs in just 2 days.
Sorry for the long post
