The text() method in the Blob interface returns a Promise that resolves with a string containing the contents of the blob, interpreted as UTF-8.

None.

A promise that resolves with a string which contains the blob's data as a text string. The data is always presumed to be in UTF-8 format.

The FileReader method readAsText() is an older method that performs a similar function. It works on both Blob and File objects. There are two key differences:

• Blob.text() returns a promise, whereas FileReader.readAsText() is an event based API.
• Blob.text() always uses UTF-8 as encoding, while FileReader.readAsText() can use a different encoding depending on the blob's type and a specified encoding name.

• Response.text()
• Streams API
• FileReader.readAsText()
