Package Exports
- onetime
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 (onetime) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
onetime 
Only call a function once
When called multiple times it will return the return value from the first call.
Unlike the module once, this one isn't naughty extending Function.prototype.
