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!

isEvalError

NPM version Build Status Coverage Status

Test if a value is an EvalError object.

Installation

npm install @stdlib/assert-is-eval-error

Usage

var isEvalError = require( '@stdlib/assert-is-eval-error' );

isEvalError( value )

Tests if a value is an EvalError object.

var bool = isEvalError( new EvalError( 'beep' ) );
// returns true

Notes

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

Examples

var isEvalError = require( '@stdlib/assert-is-eval-error' );

var bool = isEvalError( new EvalError( 'eval error' ) );
// returns true

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

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

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

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

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

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

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

bool = isEvalError( null );
// returns false
