Render Phase

๐งโโ๏ธ Hi! I made a change to the code a bit. Now we're rendering two buttons, the
count button is still there, but now we're also a button for disabling the count
button. I needed to add another
useState
for that, but it's not working. You
can check my work if you'd like. Can you get it
working? Thanks!๐จโ๐ผ Thanks for adding those buttons Kellie!
Ok, so what we need you to do is fix the problem. If you add a
console.log({ count, enabled })
to the component, you'll get
{ count: 0, enabled: 0 }
. This is because the first time the useState
is
called initializes the state and the second time it's called, it just references
the first one.So to start off fixing this issue, you're going to need to formalize how we
determine whether state gets initialized or referenced.
Really,
useState
can be called in two scenarios:- Initialization
- Updates
So we're going to keep track of how this is called with a
phase
variable. The
emoji will guide you in the right direction. Good luck!Note it's not going to quite work when you're finished with this step, but
it'll work soon!
