The onLikeToggle prop should be marked as required using isRequired. The component uses this function in the onClick handler, and failing to provide it will result in a runtime error when the button is clicked.

The PropTypes definition for entries is too generic. It should use PropTypes.arrayOf with a shape definition to properly validate the structure of the chat entries, including id, sender, body, timeStamp, and liked properties.

| entries: PropTypes.arrayOf( | |
| PropTypes.shape({ | |

The onLikeToggle prop should be marked as required using isRequired. The component relies on this function being passed in for the like functionality to work properly, and the parent component App always provides it.

All chat entries are hardcoded with the "local" class, which means all messages will appear on the left side with yellow styling. Based on the CSS file which defines both "local" and "remote" styles, the className should be dynamically determined based on which user sent the message. Consider adding logic to differentiate between local and remote messages, possibly by comparing the sender to a current user prop.

The like button is missing an accessible label. Users relying on screen readers won't know what the button does. Add an aria-label attribute such as "like" or "toggle like" to make this button accessible.
| onClick={() => props.onLikeToggle(props.id)} | |
| onClick={() => props.onLikeToggle(props.id)} | |
| aria-label={props.liked ? "unlike" : "like"} |
…ecific, re-added is required to onToggle
