+
+The **`ErrorEvent()`** constructor creates a new {{domxref("ErrorEvent")}} object.
+
+## Syntax
+
+```js-nolint
+new ErrorEvent(type)
+new ErrorEvent(type, options)
+```
+
+### Parameters
+
+- `type`
+  - : A string with the name of the event. It is case-sensitive.
+- `options` {{optional_inline}}
+  - : An object that, _in addition of the properties defined in {{domxref("Event/Event", "Event()")}}_, can have the following properties:
+    - `message` {{optional_inline}}
+      - : A string containing a human-readable error message describing the problem. Lacking a [`crossorigin`](/en-US/docs/Web/HTML/Attributes/crossorigin) setting reduces error logging.
+    - `filename` {{optional_inline}}
+      - : A string containing the name of the script file in which the error occurred.
+    - `lineno` {{optional_inline}}
+      - : An `integer` containing the line number of the script file on which the error occurred.
+    - `colno` {{optional_inline}}
+      - : An `integer` containing the column number of the script file on which the error occurred.
+    - `error` {{optional_inline}}
+      - : A JavaScript `Object` that is concerned by the event.
+
+### Return value
+
+A new {{domxref("ErrorEvent")}} object.
