title: EvalError
slug: Web/JavaScript/Reference/Global_Objects/EvalError
page-type: javascript-class
browser-compat: javascript.builtins.EvalError
sidebar: jsref
---
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](/en-US/docs/Web/API/Worker) using {{domxref("Worker/postMessage()", "postMessage()")}}.
`EvalError` is a subclass of {{jsxref("Error")}}.
## Constructor
- {{jsxref("EvalError/EvalError", "EvalError()")}}
- : Creates a new `EvalError` object.
## Instance properties
_Also inherits instance properties from its parent {{jsxref("Error")}}_.
These properties are defined on `EvalError.prototype` and shared by all `EvalError` instances.
- {{jsxref("Object/constructor", "EvalError.prototype.constructor")}}
- : The constructor function that created the instance object. For `EvalError` instances, the initial value is the {{jsxref("EvalError/EvalError", "EvalError")}} constructor.
- {{jsxref("Error/name", "EvalError.prototype.name")}}
- : Represents the name for the type of error. For `EvalError.prototype.name`, the initial value is `"EvalError"`.
## Instance methods
_Inherits instance methods from its parent {{jsxref("Error")}}_.
## Examples
### Creating an EvalError
```js
try {
throw new EvalError("Hello");
} catch (e) {
console.log(e instanceof EvalError); // true
console.log(e.message); // "Hello"
console.log(e.name); // "EvalError"
console.log(e.stack); // Stack of the error
}
```
