arrayBuffer()
None.
A promise that resolves with an ArrayBuffer
that contains the blob's data in binary form.
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.
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.
