confirmGuest = () => {
this.setState( prevState => ({
isConfirmed: !_________.isConfirmed
}));
}
Is the above saying to update the state of isConfirmed
through the negation of its previous state? So, if the previous state of isConfirmed
is false
, then we're changing it to true
with the exclamation point, right?
