One popular feature on the social networking site Facebook is a feature of 'like' and 'comment'. In general, any user can comment on any status, photos, and articles that are shared by other users. That way, users can exchange comments and discussions with other users. But such comments are often misspelled or often known as typo ( typographical error ). Writing errors in the column can not edit this comment. Typically, the user must remove the comments and then write it again properly. But no one knows if the actual Facebook allow users to perform editing this comment. Facebook gives pause 30 seconds for users who want to edit these comments. By clicking on a cross (X), the comments were going to be edited.
