App._this.toggleGuestPropertyAt
24 | ] 25 | } 26 |
27 | toggleGuestPropertyAt = (property, indexToChange) => 28 | this.state({ 29 | guests: this.state.guests.map((guest, index) => { 30 | if (index === indexToChange) {
toggleGuestPropertyAt = (property, indexToChange) => this.state({ guests: this.state.guests.map((guest, index) => { if (index === indexToChange) { return { ...guest, [property]: !guest[property] }; } return guest; }) });
toggleConfirmationAt = index => this.toggleGuestPropertyAt("isConfirmed", index);
handleConfirmation={() => props.toggleConfirmationAt(index)}
I got this error when when changing my function to use property. This happens when clicking checkbox also when clicking editing button just the different function toggleEditingAt When I searched on the internet for this error it gave me answers about how to bind this. Which I am not sure about, what do you think guys?

Treehouse Project ReviewerHi, so
state
is not a function, but rather an object we use to hold the current state of a component.setState()
is a function we use to change the state of thestate
object. It takes two arguments - the first is an object that we will merge withstate
, and the second is a callback that is basically never used.So in this case you have
this.state
instead ofthis.setState
. You need to update thestate
object with thesetState
function.Hope that helps :)
