Package Exports
- sliced
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 (sliced) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

##Usage
sliced accepts the same arguments as Array#slice so you can easily swap it out.
function zing () {
var slow = [].slice.call(arguments, 1, 8);
var args = slice(arguments, 1, 8);
var slow = Array.prototype.slice.call(arguments);
var args = slice(arguments);
// etc
}install
npm install sliced
