    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);
    });
