define-lazy-prop

Define a lazily evaluated 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

import defineLazyProperty from 'define-lazy-prop';

const unicorn = {
	// …
};

defineLazyProperty(unicorn, 'rainbow', () => expensiveComputation());

app.on('user-action', () => {
	doSomething(unicorn.rainbow);
});

Name of the property to add.
