Package Exports
- define-lazy-prop
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (define-lazy-prop) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
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.
