JavaScript: devuelve verdadero desde la función si onload inside devuelve verdadero

Tengo una función que envía una solicitud para crear una cookie cifrada. Dentro de esa función hay una función de carga.

¿Lo que necesito?
Necesito "transferir" el retorno de onload() a la función principal.

 function createCookie(method = "POST", action, parameters, token, contentType = "application/x-www-form-urlencoded") { let xhr = new XMLHttpRequest(); xhr.open(method, action, true); xhr.setRequestHeader('Content-type', contentType); xhr.onload = () => { let jsonResponse = JSON.parse(xhr.responseText); if(jsonResponse && jsonResponse['status'] == 'true') { return true; } else { return false; } } xhr.send("_token=" + token + "&" + parameters); }
