Blob()

The Blob() constructor returns a new Blob object. The content of the blob consists of the concatenation of the values given in the parameter blobParts.

Inputs: blobParts An iterable object such as an Array, having ArrayBuffers, TypedArrays, DataViews, Blobs, strings, or a mix of any of such elements, that will be put inside the Blob. Strings should be well-formed Unicode, and lone surrogates are sanitized using the same algorithm as String.prototype.toWellFormed(). The resulting string is encoded as UTF-8.

Inputs: options An object which may specify any of the following properties: type The MIME type of the data that will be stored into the blob. The default value is the empty string, (“”). endings How to interpret newline characters (n) within the contents, if the data is text. The default value, transparent, copies newline characters into the blob without changing them. To convert newlines to the host system’s native convention, specify the value native.
