function zipReadableStreams
import { zipReadableStreams } from "https://deno.land/std@0.220.0/streams/zip_readable_streams.ts";

Merge multiple streams into a single one, taking order into account, and each stream will wait for a chunk to enqueue before the next stream can append another chunk. If a stream ends before other ones, the others will continue adding data in order, and the finished one will not add any more data.

Examples

Example 1

import { zipReadableStreams } from "https://deno.land/std@0.220.0/streams/zip_readable_streams.ts";

const stream1 = ReadableStream.from(["1", "2", "3"]);
const stream2 = ReadableStream.from(["a", "b", "c"]);
const zippedStream = zipReadableStreams(stream1, stream2);

await Array.fromAsync(zippedStream); // ["1", "a", "2", "b", "3", "c"];
