MDN wants to learn about developers like you:

The setInt16() method stores a signed 16-bit integer (short) value at the specified byte offset from the start of the DataView.


dataview.setInt16(byteOffset, value [, littleEndian])


The offset, in byte, from the start of the view where to store the data.
The value to set.
Optional Indicates whether the 16-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is written.

Return value


Errors thrown

Thrown if the byteOffset is set such as it would store beyond the end of the view.


Using the setInt16 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setInt16(1, 3);
dataview.getInt16(1); // 3
