has-proto

Does this environment have the ability to set the Prototype of an object on creation with __proto__?

Example

var hasProto = require('has-proto');
var assert = require('assert');

assert.equal(typeof hasProto(), 'boolean');

var hasProtoAccessor = require('has-proto/accessor')();
if (hasProtoAccessor) {
	assert.equal([].__proto__, Array.prototype);
} else {
	assert(!('__proto__' in Object.prototype));
}

var hasProtoMutator = require('has-proto/mutator');
var obj = {};
assert('toString' in obj);

obj.__proto__ = null;
if (hasProtoMutator) {
	assert(!('toString' in obj));
} else {
	assert('toString' in obj);
	assert.equal(obj.__proto__, null);
}

Tests

Simply clone the repo, npm install, and run npm test
