About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
isSyntaxError
Test if a value is a SyntaxError object.
Installation
npm install @stdlib/assert-is-syntax-error
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 aSyntaxError
(or a descendant) object, false positives may occur due to the fact that theSyntaxError
constructor inherits fromError
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
