Example 4-2

There is a line: textarea = this.result; This does not work. On run it reports error "Uncaught NotFoundError: An attempt was made to reference a Node in a context where it does not exist." That line should be textarea.value = this.result;

Example 4-3

Code from example does not work any more. It seems that BlobBuilder is obsoleted. Blob should be used instead. The following lines: var bb = new BlobBuilder(); // Create a new Blob on-the-fly. bb.append('Lorem Ipsum'); fileWriter.write(bb.getBlob('text/plain')); could be changed to, for example: fileWriter.write(new Blob(["Lorem Ipsum"], { type: "text/plain" }));

Note from the Author or Editor:
Yep. BlobBuilder was removed and replaced by the Blob() constructor.
