The byteOffset accessor property represents the offset (in bytes) of this view from the start of its ArrayBuffer or SharedArrayBuffer.
dataview.byteOffset
The byteOffset property is an accessor property whose set accessor function is undefined, meaning that you can only read this property. The value is established when an DataView is constructed and cannot be changed.
byteOffset propertyvar buffer = new ArrayBuffer(8); var dataview = new DataView(buffer); dataview.byteOffset; // 0 (no offset specified) var dataview2 = new DataView(buffer, 3); dataview2.byteOffset; // 3 (as specified when constructing the DataView)
