Readable Streams

Consume data chunk by chunk.

What Are Streams?

The Streams API processes data incrementally as chunks arrive, rather than loading everything into memory. This enables handling huge downloads, video, and live feeds efficiently.

The ReadableStream

A ReadableStream is a source you read from chunk by chunk. Browsers expose them on fetch responses, file blobs, and more.
