Returning true if JavaScript array contains an element

Question

So far I have this code:

var isMatch = viewedUserLikedUsersArray.indexOf(logged_in_user);
    if (isMatch >=0){
      console.log(\'is match\');
    }
    els         


        

Answer 1

You could just use Array.prototype.some

var isMatch = viewedUserLikedUsersArray.some(function(user){
  return user === logged_in_user;
});

It stops when it finds a true value
