Syntax
setInt8(byteOffset, value)
Parameters
byteOffset- : The offset, in bytes, from the start of the view to store the data in.
value- : The value to set. For how the value is encoded in bytes, see Value encoding and normalization.
Return value
Exceptions
- RangeError
- : Thrown if the
byteOffsetis set such that it would store beyond the end of the view.
- : Thrown if the
Examples
Using setInt8()
const buffer = new ArrayBuffer(10);
const dataview = new DataView(buffer);
dataview.setInt8(0, 3);
dataview.getInt8(0); // 3
