4.8 use one state has the place and what is bette
Fine instead of calling it that now
we will pass on a function to him, that is to say already All this we can do.
As before, put it in comment we are going to give it a set User input function
inside the parentheses you add
parentheses and in the first parentheses
we’ll do a function with arrows
and we’re gonna put some brackets like this on you have called a user input function defines
and you analyze it for example a function.
Anonymously and thus the malfunctions you have used to set user input here this will be automatically executed
by reacting it will receive the snapshot
previous state for that state for which you call the update function you put prev state
so what is prevstate to explain you
it’s just a parameter to the callback function
you stored it in a native way to react
then we go inside the bracket we go return bracket three small dots like everything to
the time
prev state like this and here we go let alone we’ll put our friend
entered title
and we’ll put the event with target as always.value
now you can do several scenarios
so what we’re gonna do now is here we’re gonna put back our const and that’s what we’re going to put
this time comment it’s something you must keep in mind in general when you depend often of a state
only if you have given a status like this one. In other scenarios as to counter what I mentioned
that’s why I still talk about it back now to this multi-state approach.
