# define-lazy-prop
|
||||
|
||||
> Define a [lazily evaluated](https://en.wikipedia.org/wiki/Lazy_evaluation) property on an object
|
||||
|
||||
Useful when the value of a property is expensive to generate, so you want to delay the computation until the property is needed. For example, improving startup performance by deferring nonessential operations.
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
$ npm install define-lazy-prop
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
import defineLazyProperty from 'define-lazy-prop';
|
||||
|
||||
const unicorn = {
|
||||
// …
|
||||
};
|
||||
|
||||
defineLazyProperty(unicorn, 'rainbow', () => expensiveComputation());
|
||||
|
||||
app.on('user-action', () => {
|
||||
doSomething(unicorn.rainbow);
|
||||
});
|
||||
```
|
||||
|
||||
