Blob: arrayBuffer() method
The arrayBuffer() method in the Blob
interface returns a Promise that resolves with the contents of the blob as
binary data contained in an ArrayBuffer.
Syntax
js
arrayBuffer()
Parameters
None.
Return value
A promise that resolves with an ArrayBuffer that contains the blob's
data in binary form.
Exceptions
While this method doesn't throw exceptions, it may reject the promise. This can happen, for example, if the reader used to fetch the blob's data throws an exception. Any exceptions thrown while getting the data will be converted into rejections.
Usage notes
While similar to the FileReader.readAsArrayBuffer() method,
arrayBuffer() returns a promise rather than being an event-based API, as is
the case with the FileReader interface's method.
