# 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); }); ``` ## API ### defineLazyProperty(object, propertyName, valueGetter) #### object Type: `object` Object to add the property to. #### propertyName Type: `string` Name of the property to add. #### valueGetter Type: `Function` Called the first time `propertyName` is accessed. Expected to return a value. ## Related - [lazy-value](https://github.com/sindresorhus/lazy-value) - Create a lazily evaluated value - [import-lazy](https://github.com/sindresorhus/import-lazy) - Import a module lazily - [p-lazy](https://github.com/sindresorhus/p-lazy) - Create a lazy promise
