SyntaxError() constructor

The SyntaxError() constructor creates SyntaxError objects.

Syntax

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

SyntaxError()
SyntaxError(message)
SyntaxError(message, options)
SyntaxError(message, fileName)
SyntaxError(message, fileName, lineNumber)

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

Catching a SyntaxError

js
try {
  eval("hoo bar");
} catch (e) {
  console.log(e instanceof SyntaxError); // true
  console.log(e.message);
  console.log(e.name); // "SyntaxError"
  console.log(e.stack); // Stack of the error
}

Creating a SyntaxError

js
try {
  throw new SyntaxError("Hello");
} catch (e) {
  console.log(e instanceof SyntaxError); // true
  console.log(e.message); // "Hello"
  console.log(e.name); // "SyntaxError"
  console.log(e.stack); // Stack of the error
}
