A wrapper over JS iterator, which allows filter/map/etc with chaining.
Usage: Example:
const sourceIter = (async function* () {
for await (const item of [1, 2, 3, 4, 5]) {
yield item;
}
})();
const asyncIter = new AsyncIter(sourceIter);
const iter =
asyncIter
.filter((item) => item % 2 === 0)
.filter((item) => item > 2)
.map((item) => item * 2)
.map((item) => item + 1)
.mapAsync(async (item) => item / 3)
;
const result = [];
for await (const item of iter) {
result.push(item);
}
expect(result).to.deep.equal([3]);
