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

EvalError is a serializable object, so it can be cloned with structuredClone() or copied between Workers using postMessage().

EvalError is a subclass of Error.

These properties are defined on EvalError.prototype and shared by all EvalError instances.
