EvalError() constructor
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.
The EvalError() constructor creates EvalError objects.
Syntax
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
messageOptional-
Human-readable description of the error.
optionsOptional-
An object that has the following properties:
causeOptional-
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.
fileNameOptional Non-standard-
The name of the file containing the code that caused the exception
lineNumberOptional Non-standard-
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
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
}
