Comprobar si la imagen src es válida

Estoy tratando de verificar si la URL de una imagen es válida antes de configurar mi img src. De momento esto es lo que tengo:

 function checkURL(url) { var img = new Image(); img.onerror = function () { return false; } img.onload = function () { return true; } img.src = url; }

En ambos casos, se devuelve undefined en lugar de true/false .

Aquí hay un violín

¿Qué puedo hacer para resolver mi problema? Estoy usando jQuery 3.6.0.
