isReferenceError

Test if a value is a ReferenceError object.

Usage

var isReferenceError = require( '@stdlib/assert/is-reference-error' );

isReferenceError( value )

Tests if a value is a ReferenceError object.

var bool = isReferenceError( new ReferenceError( 'beep' ) );
// returns true

Notes

  • This function should not be considered robust. While the function should always return true if provided a ReferenceError (or a descendant) object, false positives may occur due to the fact that the ReferenceError constructor inherits from Error and has no internal class of its own. Hence, ReferenceError impersonation is possible.

Examples

var isReferenceError = require( '@stdlib/assert/is-reference-error' );

var bool = isReferenceError( new ReferenceError( 'reference error' ) );
// returns true

bool = isReferenceError( new Error( 'error' ) );
// returns false

bool = isReferenceError( new EvalError( 'eval error' ) );
// returns false

bool = isReferenceError( new RangeError( 'range error' ) );
// returns false

bool = isReferenceError( new SyntaxError( 'syntax error' ) );
// returns false

bool = isReferenceError( new TypeError( 'type error' ) );
// returns false

bool = isReferenceError( new URIError( 'URI error' ) );
// returns false

bool = isReferenceError( {} );
// returns false

bool = isReferenceError( null );
// returns false
