Does this environment have the ability to set the [[Prototype]] of an object on creation with `__proto__`?
|
|
|
|
## Example
|
|
|
|
```js
|
|
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);
|
|
}
|
|
```
|
|
|
|
