setInt8(byteOffset, value)
byteOffsetThe offset, in bytes, from the start of the view to store the data in.
valueThe value to set. For how the value is encoded in bytes, see Value encoding and normalization.
RangeErrorThrown if the byteOffset is set such that it would store beyond the end of the view.
const buffer = new ArrayBuffer(10); const dataview = new DataView(buffer); dataview.setInt8(0, 3); dataview.getInt8(0); // 3
