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!

isCircularPlainObject

NPM version Build Status Coverage Status

Test if a value is a plain object containing a circular reference.

Installation

npm install @stdlib/assert-is-circular-plain-object

Usage

var isCircularPlainObject = require( '@stdlib/assert-is-circular' );

isCircularPlainObject( value )

Tests if a value is a plain object containing a circular reference.

var obj = {
    'beep': 'boop'
};
var bool = isCircularPlainObject( obj );
// returns false

obj.self = obj;
bool = isCircularPlainObject( obj );
// returns true

Examples

var isCircularPlainObject = require( '@stdlib/assert-is-circular' );

var obj1 = {
    'a': 'beep',
    'b': {
        'c': 'boop'
    }
};
obj1.b.self = obj1;
var bool = isCircularPlainObject( obj1 );
// returns true

var obj2 = {
    'a': {},
    'b': obj1
};
bool = isCircularPlainObject( obj2 );
// returns true

var arr = [ 1, 2, 3 ];
arr.push( arr );
bool = isCircularPlainObject( arr );
// returns false

var obj3 = {
    'beep': 'boop'
};
bool = isCircularPlainObject({
    'a': obj3,
    'b': obj3
});
// returns false

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

bool = isCircularPlainObject( null );
// returns false
