EvalError

The EvalError object indicates an error regarding the global {{jsxref("Global_Objects/eval", "eval()")}} function. This exception is not thrown by JavaScript anymore, however the EvalError object remains for compatibility.

EvalError is a {{Glossary("serializable object")}}, so it can be cloned with {{DOMxRef("Window.structuredClone", "structuredClone()")}} or copied between Workers using {{domxref("Worker/postMessage()", "postMessage()")}}.

EvalError is a subclass of {{jsxref("Error")}}.
