# get-own-enumerable-property-symbols [](https://travis-ci.org/mightyiam/get-own-enumerable-property-symbols)
|
|
|
|
Returns an array of all *enumerable* symbol properties found directly upon a given object.
|
|
|
|
Similar to [`Object.getOwnPropertySymbols`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/getOwnPropertySymbols)
|
|
but only [enumerable](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Enumerability_and_ownership_of_properties) keys.
|
|
|
|
```js
|
|
import getOwnEnumPropSymbols from 'get-own-enumerable-property-symbols'
|
|
|
|
getOwnEnumPropSymbols({ [Symbol()]: undefined })
|
|
// [Symbol()]
|
|
getOwnEnumPropSymbols(Object.defineProperty({}, Symbol(), {enumerable: false}))
|
|
// []
|
|
```
