State, 1/3)
Avoid using multiple setState's for combined data models, especially in async functions as they re-render per setState.

Instead, combine into a single setState for simple state logic.

🔥🔥🔥 The #1 Recursion (Syntax) Twitter Thread
This thread will demonstrate an easy way to write recursive functions
The recursion will so be compared to a for loop for familiarity
Tail Calls and Performance discussed later, Syntax Only!

Step 1: Create your iteration variable(s)
In recursion, it can be easier to set a default value. Pass `i` again when calling `loop` on the `return` line

Step 2: Add a break condition
Like a for loop, add the break before you write your code. This will prevent infinite looping.
Notice how the for loop is a "continue" and the recursion uses a "break". That means the condition must be flipped for recursion

👁️👁️Watch me refactor an simple API in four simple steps. (a twitter thread). ⚠️Warning, may contain currying and partial application 😉

Refactoring Step 1: Eliminate the code `.then(response => response.data)` in each function by extracting this to a function called `getResponseData`.

Refactoring Step 2: Eliminate the URLs from each function by extracting this to a function called `createUrl`. The function will create a url based off the category and id.

I'm learning @reactjs and it's ecosystem. I will share my learning journey here as a thread.

I will give some context first. I have been working with Java and contributing for Python open source projects like #SerenataDeAmor in the last 3 years. I already knew some frontend but it have changed a lot during this time.
Now I'm coming back to this world though @reactjs because of my new engagement @thoughtworksbr
