isURIError

Test if a value is a URIError object.

Usage

var isURIError = require( '@stdlib/assert/is-uri-error' );

isURIError( value )

Tests if a value is a URIError object.

var bool = isURIError( new URIError( 'beep' ) );
// returns true

Notes

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

Examples

var isURIError = require( '@stdlib/assert/is-uri-error' );

var bool = isURIError( new URIError( 'URI error' ) );
// returns true

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

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

bool = isURIError( new ReferenceError( 'reference error' ) );
// returns false

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

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

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

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

bool = isURIError( null );
// returns false
