| 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 |
| ``` |
