示例1: Set
static _intersection<T>(iter: IIterator<Array<T>>): Set<T> | void {
// pop the first element of iter
let first = iter.next();
// first will be undefined if iter is empty
if (!first) {
return;
}
// "initialize" the intersection from first
let isect = new Set(first);
// reduce over the remaining elements of iter
return reduce(
iter,
(isect, subarr) => {
// filter out all elements not present in both isect and subarr,
// accumulate result in new set
return new Set(subarr.filter(x => isect.has(x)));
},
isect
);
}示例2: it
it('should invoke the reducer if the iterable has just two items with no initial value', () => {
let data = [1, 2];
let result = reduce(data, (a, x) => a + x);
expect(result).to.equal(3);
});示例3: reduce
let reduced = () => reduce(data, (a, x) => a + x);
