isSyntaxError

Test if a value is a SyntaxError object.

Usage

var isSyntaxError = require( '@stdlib/assert/is-syntax-error' );

isSyntaxError( value )

Tests if a value is a SyntaxError object.

var bool = isSyntaxError( new SyntaxError( 'beep' ) );
// returns true

Notes

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

Examples

var isSyntaxError = require( '@stdlib/assert/is-syntax-error' );

var bool = isSyntaxError( new SyntaxError( 'syntax error' ) );
// returns true

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

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

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

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

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

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

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

bool = isSyntaxError( null );
// returns false
