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

let booleanAnd = arrayreduce.booleanAnd();
// Execute reducing.
let result = [true, false, true].reduce(booleanAnd, true);
console.log(result); // -> false
Boolean Or
arraysort.booleanOr() create a function which reduce entries with and condition.

let result = [true, false, true].reduce(booleanOr, true);
console.log(result); // -> true
Index By Attr

let index = [
{id: 1, name: 'foo'},
