wish of those help Instead of a local variable inside the filterPortfolio try moving filterPortfolioIsRunning to the global space or use the data method and store it in an element, like this:
code :
function filterPortfolio() {
  $('[data-filter]').on('click', function() {
    var filterPortfolioIsRunning = true;
    // to stuff then save in the element...
    $('[data-filter]').data('filter', filterPortfolioIsRunning);
  });
}
function revealProject() {
  if ( $('[data-filter]').data('filter') ) {
    // no global variables prevent name collision!
  }
}

I hope this helps . You will have to read up on async execution. The success block is run when the ajax call is 'complete, but the execution of your code will continue right away after the $.ajax() call.
The reason for the undefined error is that the method doesn't return anything unless you ad the 'return false' call.
is there any way to check ajax function return value is true or false?

may help you . i'm trying to build a signup form there i need to check that the value of load function of ajax is true or false. , you must echo true or false in json format. sth like this.
code :
<?php

     $result = array();
     $mail=$_POST["email"];
     $db=new PDO("mysql:host=localhost;dbname=the_scops","root","");
     $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
     $STH=$db->prepare("SELECT email FROM signup WHERE email=?");
     $STH->execute([$mail]);
     if($STH->rowCount() == 1){    
         $result['status'] = false;
     }
     else{
         $result['status'] = true;
     }

     echo json_encode($result);
     exit(0);

?>
$("button").click(function(){
   $("#error").load("newEmptyPHP.php",{email:mail},function(response){
       result = $.parseJSON(response);
       if(result.status){
           //true
       } else {
           //false
       }
   });
});

like below fixes the issue You can give while a function, but while isn't going to call your function. It will regard a function as a truthy value and hence continue endlessly. You'll have to call your function yourself. But really, that is nonsense, you just have to use an expression which results in true or false, in this case Array.prototype.some is what you're looking for:
code :
do {
   ...
} while (kategoriak.some(elem => elem.szint === 0));

will be helpful for those in need This is impossible to answer with just the information given.
The correct answer is whatever function1 expects. The function takes some information and returns a value based on that. Without knowing what the function does or how it does it, it's impossible to answer.
