Besides the generic Error constructor that can be used to create custom errors, there are seven other core error constructors in JavaScript. These are −

  • EvalError −Creates an instance representing an error that occurs regarding the global function eval().

  • InternalError −Creates an instance representing an error that occurs when an internal error in the JavaScript engine is thrown. For Example: "too much recursion"

  • RangeError  − Creates an instance representing an error that occurs when a numeric variable or parameter is outside of its valid range.

  • ReferenceError −Creates an instance representing an error that occurs when de-referencing an invalid reference.

  • SyntaxError −Creates an instance representing a syntax error that occurs while parsing code in eval().

  • TypeError −Creates an instance representing an error that occurs when a variable or parameter is not of a valid type.

  • URIError −Creates an instance representing an error that occurs when encodeURI() or decodeURI() are passed invalid parameters.
