How to use the if else conditional loop?

Question

I need some help in this conditional code. In order to store the required data to the variable paw, I have three conditions.

If nameu is not blank or empty and empidu is blank or empty, it should store the Title : nameu only.
Else if nameu is blank or empty and empidu is not blank or empty, it should store the EmpID : empidu only.
Else store both.

I have written the code myself, but it is not working. Here is the code :

var paw = "";
    if(nameu !== " ") {
       paw = JSON.stringify({
        Title: nameu
      });
    }
    else if(nameu === "" & empidu !== " ") {
       paw = JSON.stringify({
        EmpID: empidu
      });
    }
    else {
     paw = JSON.stringify({
      Title: nameu,
      EmpID: empidu,
    });
  }

Note : nameu (String) and empidu (number) are user input values

I think I am either writing wrong statements or logic. Please help me.

You should use logical AND operator (&&) to evaluate multiple expressions instead of bitwise AND (&)

you can use this code

    let paw = {};
    if (nameu.trim() !== ''){
       paw.Title=nameu;
    }
    if (empidu.trim() !== ''){
       paw.EmpID = empidu;
    }
    paw = JSON.stringify(paw);

Thank you for your answer. But adding && worked for me. Here is the code :

var paw = "";     if(nameu !== " " && empidu === "") {        paw = JSON.stringify({         Title: nameu       });     }     else if(nameu === "" && empidu !== " ") {        paw = JSON.stringify({         EmpID: empidu       });     }     else {      paw = JSON.stringify({       Title: nameu,       EmpID: empidu,     });   }
