Code requires a programmer to design, write, and maintain. Sometimes writing code is necessary, but often all that is needed is simple data, not complex code.

Code requires a programmer to design, write, and maintain. Sometimes writing code is necessary, but often all that is needed is simple data, not complex code. HTML is data. It has value in not requiring programmers to write it. Instead it can be written by designers, or generated by other programs, including visual tools. Yes, code can also be generated by tools, but writing code to generate code is a more difficult task than writing code to generate data. Except for Lisp of course, where code and data are the same.
