Tell us what’s happening:
Hello everyone, I managed to make most of the main behaviour to work.
When I click the New Quote button, a new quote comes.
However, I am struggling to load the first quote.
I divided my code in two main functions
to call the API and bring the quotes. And
To bring a new random quote whenever the button is clicked.
My plan was to call getQuotes() on the componentDidMount(), and then, immediately after, call getNewQuote(), to bring the first random quote.
The call to getQuotes() is working as I expected. But the call to getNewQuote() is not.
Please uncomment the line in the code so you can see what is happening.
Your code so far

Challenge: Build a Random Quote Machine

I’ve tried another variation with componentDidUpdate().
Giving a different error:
You can’t call
getNewQuote sets state which causes a an update (re-render) which triggers
componentDidUpdate, which in turn calls
getNewQuote and so on and so forth.
getNewQuote inside the last
.then() after the state update.
As an aside, the two arguments to the setState updater function is state and props. Naming the props argument
randomIndex doesn’t change that fact and is just confusing, especially when you have an outer variable named the same. The props argument is just an empty object anyway in this case, as there are no props.
Setting the index and using it in the same setState call also reads a little confusing. The way you have it set up means the initial quote is always the same (initial state value of
indexQuote). I would rename or remove the props argument and use the
randomIndex variable you are assigning a random index to in the outer scope instead.
That’s awesome @lasjorg! Thanks for the clear explanation and also thank you also for observing the indexQuote thing. Indeed, there were some leftovers of the things I was trying.
