 | |
| > Force V8 to use fast properties for an object
 | |
| 
 | |
| [Read more.](http://stackoverflow.com/questions/24987896/)
 | |
| 
 | |
| 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
 | |
| ```
