Parsing error: unexpected token, expected
}
on the {
of constrctor(props){
I have some other class above this one doing the same thing as constructor(props)
but no error
if I add }
before this class, no matter how many }
I added, the error is the same.
if I add {
before this class, and }
after it, it is ok, but the class below this one would show the same error on constructor
After I tried to add {}
too surround each class below, it would show

Is the Class
key word upper case in your code? It should be class
. The error message is not clear about it but maybe this is the problem.
I don't think that way of returning something in your CommentRow
's render function is valid, even though technically the variable yourcomment
is the opening <tr>
tag it's needing. (You also had a few other small syntax errors in your JSX).
Instead try to have the <tr>
there and conditional add props to it, like so:
render() {
const { comment } = this.props;
const { name } = this.state;
return (
<tr _id={comment._id} onDoubleClick={comment.name === name && this.DeleteComment}>
<td>{comment.time}</td>
<td>{comment.name}</td>
<td><p> said: </p></td>
<td id="comentcontent">{comment.content}</td>
</tr>
);
}
