IdeaGrave

A graveyard for ideas.

This project is intended as solo practice in learning Functional Programming (after coming from a background of OOP).

Setup

1. Fork and clone
2. Install dependencies (npm i)
3. Start up the parcel server using npm start
4. Navigate to localhost:1234 in your browser to view.

Takeaways & Questions

At this point, I still have way more questions than takeaways, but here's what I've gleaned thus far:

• Whenever possible, create copies of data rather than mutating them.
  • In this app, rather than pushing a new idea into the ideas array directly, I used map to create a copy, pushed into the copy, and then reassigned the original ideas variable to the copy.
• Break functionality into individual steps
  • I created several functions to execute individual steps.
  • Then the functions are composed to execute a complex task.
  • An example of this is in handleSubmit on line 41.

Questions:

• Is this functional???????? That's the big one lol
• Touching the DOM feels non-functional and full of possible side effects
  • How do we interact with the DOM as functionally as possible?
    • Answer: separate files so DOM interactions are limited to one place
• I replicated a pipelining function but can't figure out how to use it to replace line 41
  • Note: this was removed in a recent commit.
  • The tripping point is the need for the two retrieveData calls, one for the title input and one for the description input.
  • Is it better to refactor the retrieveData function to handle both at once, combining with the makeIdea function?
  • Or is it better to leave it as is, and to adjust the pipelining function?

Reflections

Reflections for the Week 5 FE Team Summit.

To Dos

1. Break index.js into multiple files
   a. Move DOM functionality into its own file
   b. Move data model manipulation into its own file
2. Create getters and setters for ideas and a singular idea
3. Wrap functionality in a function
4. Move query selectors into functions
