DataView.prototype.getUint16()
The getUint16()
method of DataView
instances reads 2 bytes starting at the specified byte offset of this DataView
and interprets them as a 16-bit unsigned integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.
Try it
Syntax
js
getUint16(byteOffset)
getUint16(byteOffset, littleEndian)
Parameters
byteOffset
-
The offset, in bytes, from the start of the view to read the data from.
littleEndian
Optional-
Indicates whether the data is stored in little- or big-endian format. If
false
orundefined
, a big-endian value is read.
Return value
An integer from 0 to 65535, inclusive.
Exceptions
RangeError
-
Thrown if the
byteOffset
is set such that it would read beyond the end of the view.
Examples
Using getUint16()
js
const { buffer } = new Uint8Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
const dataview = new DataView(buffer);
console.log(dataview.getUint16(1)); // 258
