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
|
|
```
