var mySlicedBlob = myBlob.slice( 5, 10 );
console.log( mySlicedBlob.toString() );
// XXXXXvar myBlob = new Blob( 20 , 88, 'application/octet-stream' );
console.log( myBlob.toString() );
// XXXXXXXXXXXXXXXXXXXX
var mySlicedBlob = myBlob.slice( 0, -5 );
console.log( mySlicedBlob.toString() );
// XXXXXXXXXXXXXXXvar myFile = new File( 'PROJECT/bootstrap.js' );
var myBlobSlice = myFile.slice( 0, 100 );
console.log( myBlobSlice.toString() );(default: 0)
