Looking at each block, there is far too much bespoke (Custom) code in each one. In other words, each block is unique.

However, these blocks are not unique, and instead they are functionally composed in a hierarchy, from simple to complex.

The functions the code has to complete in any single is very simple, its a series of steps to achieve the block function (e.g. deinie inputs, process inputs, produce outputs).

Thereby we can reconstruct all of the code into a set of simplified templates, where the same code is always used to perform the same task. Rather than rewriting each block using custom code, any function can be create by cutting and pasting basic elements
