The getUint16() method gets an unsigned 16-bit integer (unsigned short) at the specified byte offset from the start of the DataView.

Syntax

dataview.getUint16(byteOffset [, littleEndian])

Parameters

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

Return value

An unsigned 16-bit integer number.

Errors thrown

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