EvalError() constructor

The EvalError() constructor creates EvalError objects.

Syntax

js
new EvalError()
new EvalError(message)
new EvalError(message, options)
new EvalError(message, fileName)
new EvalError(message, fileName, lineNumber)

EvalError()
EvalError(message)
EvalError(message, options)
EvalError(message, fileName)
EvalError(message, fileName, lineNumber)

Note: EvalError() can be called with or without new. Both create a new EvalError instance.

Parameters

message Optional

Human-readable description of the error.

options Optional

An object that has the following properties:

cause Optional

A property indicating the specific cause of the error. When catching and re-throwing an error with a more-specific or useful error message, this property can be used to pass the original error.

fileName Optional

The name of the file containing the code that caused the exception

lineNumber Optional

The line number of the code that caused the exception

Examples

EvalError is not used in the current ECMAScript specification and will thus not be thrown by the runtime. However, the object itself remains for backwards compatibility with earlier versions of the specification.

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
}
