You can use the filter function and search for the same CommentId.

const replycomment = {
  CommentId: 67,
  PostId: 2,
  ReplyCommentId: 32,
  User: {id: 3, nickname: "스티브잡스"},
  UserId: 3,
  active: "1",
  content: "11",
  createdAt: "2021-03-14T11:27:57.000Z",
  id: 96,
  updatedAt: "2021-03-15T07:35:20.000Z",
}; 
            
const ReplyComments = [
  {id: 30, CommentId: 66},
  {id: 32, CommentId: 67},
  {id: 33, CommentId: 78},
  {id: 34, CommentId: 78},
  {id: 35, CommentId: null},
  {id: 36, CommentId: null},
  {id: 37, CommentId: null},
  {id: 43, CommentId: 66},
];                          
const res = ReplyComments.filter((e) => e.CommentId == replycomment.CommentId);
console.log('res', res);
