Set the proper goals. The end state is some software product, such as a website. Far too common beginners will attempt to redefine the goal to something more familiar, something like "how to write code". There are people who spend their entire careers mastering exactly how to write the code. This can be described as "expert beginners".

Somebody needs to be the adult in the room and stop the children from running the daycare. As developers we should already know how to write code, or know how to figure it out, and that shouldn't be open to discussion. The discussion must only be upon defining the goals and stepping backwards one step at a time. This is called planning and proper planning will ensure the necessary automated checks are in place. Then "how to write the code" becomes straight forward as it either conforms to the automated checks or becomes a matter for discussion.
