Javascript How to hide a function from my web app (by using php?)

I am making a web app that has typical javascript structure below. I must hide at least a function or some formulas from the public code because someone can save the page on his computer without paying for the web app membership. I am not sure how to do that.

"edit" I found the answer and is in the following snippet. My problem now is how to pass the data outside the $.post( )?

   function analysis(){
          var  L = "sting";
          var  w   = JSON.stringify(w);
          var  counter = "sting";
  $.post('../php/solver2.php',{L : L , w : w , counter:counter },
 function(data){  jdata  = JSON.parse(data); });
     
            var jdata  = JSON.parse(tempJdata);
            var x          = jdata.x;
            var v          = jdata.v;
       
       return [x v];
 }

You can't stop someone to download your client side script code.

Check this How do I hide javascript code in a webpage?

And i can check every client side code with the browser developer tools.

Edit: You mean this:

How do I pass JavaScript to PHP?

Sending a JavaScript array to PHP via POST

Pass Javascript Array -> PHP

This are your HTTP request methods(check for browser compatibility):

HTTP request methods

Every operation on the server-side is hidden(on a normal way without bugs or something else) and the result you send to the client is public.

Use JSON.stringify() on your array and use AJAX to send it to your php script.

On php side, you can json_decode() that same array and work with it.

You could protect that PHP script with sessions, and return an error if one is not allowed to access it.

I found the answer sending multiple arrays to php process them and return processed arrays.

          var  L = "sting";
          var  w   = JSON.stringify(w);
          var  counter = "sting";
  $.post('../php/solver2.php',{L : L , w : w , counter:counter },
 function(data){  var jdata  = JSON.parse(data);
                  var x          = jdata.x;
                  var v          = jdata.v;});
