Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
* Some parts of this feature may have varying levels of support.
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.
Also inherits instance properties from its parent Error.
These properties are defined on EvalError.prototype and shared by all EvalError instances.
EvalError.prototype.constructor-
The constructor function that created the instance object. For EvalError instances, the initial value is the EvalError constructor.
EvalError.prototype.name-
Represents the name for the type of error. For EvalError.prototype.name, the initial value is "EvalError".
Inherits instance methods from its parent Error.
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
}
