# rong_buffer
Implements the Web Blob and File APIs for binary data handling.
## JS APIs
- `Blob` — immutable raw binary data
- `new Blob(parts?, options?)` — create from arrays, strings, or other blobs
- `size` — byte length
- `type` — MIME type
- `slice(start?, end?, contentType?)` — create a sub-blob
- `arrayBuffer()` — read contents as `ArrayBuffer`
- `text()` — read contents as UTF-8 string
- `bytes()` — read contents as `Uint8Array`
- `File` — extends `Blob` with a filename and timestamp
- `new File(bits, name, options?)` — create a named file blob
- `name` — file name
- `lastModified` — last modified timestamp in milliseconds
