Hello, I see others have posted about this same problem. I tried going through their solutions but no luck. I don't know what I did wrong. My app works until I check the checkbox, then I get this syntax error: TypeError: props.toggleConfirmationAt is not a function. Can anyone help? Thanks!
In App.js
toggleConfirmationAt = (indexToChange) =>
this.setState({
guests: this.state.guests.map((guest, index) => {
if (index === indexToChange) {
return {
...guest,
isConfirmed: !guest.isConfirmed
};
}
return guest;
})
});
In GuestList.js:
import React from 'react';
import PropTypes from 'prop-types';
import Guest from './Guest';
const GuestList = (props) => {
return (
<ul>
{props.guests.map((guest, index) => (
<Guest
key={index}
name={guest.name}
isConfirmed={guest.isConfirmed}
handleConfirmation={() => props.toggleConfirmationAt(index)}
/>
))}
</ul>
);
};
GuestList.propTypes = {
guests: PropTypes.array.isRequired,
toggleConfirmationAt: PropTypes.func.isRequired
};
export default GuestList;
In Guest.js:
import React from 'react';
import PropTypes from 'prop-types';
const Guest = props => {
return (
<li>
<span>{props.name}</span>
<label>
<input
type="checkbox"
checked={props.isConfirmed}
onChange={props.handleConfirmation}
/>
Confirmed
</label>
<button>edit</button>
<button>remove</button>
</li>
);
};
Guest.propTypes = {
name: PropTypes.string.isRequired,
isConfirmed: PropTypes.bool.isRequired,
handleConfirmation: PropTypes.func.isRequired
};
export default Guest;

12,209 PointsOk I solved my own problem here...of course it was a typo!!!
Down in App.js, here was my problem. I fixed it and it works now :)
<GuestList
guests={this.state.guests}
toggleConfirmationAt={this.toggleCoirmationAt}
/>
</div>
</div>
