constructor cljs

Constructor.

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

array is an js.Array of js.ArrayBuffer, web.typed.ArrayBufferView, web.files.Blob, web.dom.DOMString objects, or a mix of any of such objects, that will be put inside the web.files.Blob. DOMStrings are encoded as UTF-8. options is an optional BlobPropertyBag dictionary which may specify the following two attributes:

type, with a default value of "", that represents the MIME type of the content of the array that will be put in the blob. endings, with a default value of "transparent", that specifies how strings containing the line ending character \n are to be written out. It is one of the two values: "native", meaning that line ending characters are changed to match host OS filesystem convention, or "transparent", meaning that endings are stored in the blob without change.
