Explain the init function earlier

[senorsmile]

About me:

• My programming background is in systems programming.
• I want to learn Elm because it seems to be a good starting point into front end development, especially for those of us where FP, immutability are important.
• I was confused by the init function. This delayed understanding lead to being confused about several other things as well.

We first come upon the init function in the architecture/buttons chapter. However, the first time the init function is explained, is when it starts being used in a different way in the effects/http chapter.

I can assume that this must just make sense in the context for those familiar with front end development. Once I got to the effects/http chapter, I was already fairly confused, but decided to continue on. Going back from the beginning of the back to that point again made things clearer.
