Well there's a considerable amount of "drag & drop" app builders that write the code for the developer....... so yes there are apps that build the underlying code for you.

MIT developed their Scratch introductory "coding" program for elementary students but most students at that age will rarely be introduced to the actual code layered underneath. All it does is help develop logic and problem solving skills for students as they drop and connect simple commands to turn left, move forward 2 steps, etc.

Also consider all the gaming engines developers use that have all the coding hidden underneath that the developer uses in the interface of menu items.

Do you even realize there's script and code used in the background allowing this webpage to display your post?

I would assume that all software developers have a base software engine to easily write the majority of their code and only make small refinements when needed.
