Use `%HasFastProperties(object)` and `--allow-natives-syntax` to check whether an object already has fast properties. |
|
|
|
|
|
## Install |
|
|
|
``` |
|
$ npm install --save to-fast-properties |
|
``` |
|
|
|
|
|
## Usage |
|
|
|
```js |
|
const toFastProperties = require('to-fast-properties'); |
|
|
|
const obj = { |
|
foo: true, |
|
bar: true |
|
}; |
|
|
|
delete obj.foo; |
|
// `obj` now has slow properties |
|
|
|
toFastProperties(obj); |
|
// `obj` now has fast properties |
|
``` |
