Hi, this is my first post and im here to ask some questions about web programming and design.
I am interested in coding websites, I find it super enjoyable by somehow making things work just by typing a code.

Is it worth learning all the languages like HTML, JS, XML, etc... now that there are websites out like Weebly or Wix?
People can just make their own websites without any coding knowledge just by using sites like Weebly and wix so why would they hire me?

Where would I work? In an office? at home? Where do I find work? Is this like a self employment type of career path?

What kind of code languages should a newbie start learning without any coding knowledge? Where should I start?
Do i need to go to school/college for this career choice? Should i be certified?

Thank you to all who helped!
