ThegetInt16() method ofDataView instances reads 2 bytes starting at the specified byte offset of thisDataView and interprets them as a 16-bit signed integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

Try it

// Create an ArrayBuffer with a size in bytesconst buffer = new ArrayBuffer(16);const view = new DataView(buffer);view.setInt16(1, 32767); // Max signed 16-bit integerconsole.log(view.getInt16(1));// Expected output: 32767

Syntax

getInt16(byteOffset)getInt16(byteOffset, littleEndian)

Parameters

byteOffset

The offset, in bytes, from the start of the view to read the data from.

littleEndianOptional

Indicates whether the data is stored inlittle- or big-endian format. Iffalse orundefined, a big-endian value is read.

Return value

An integer from -32768 to 32767, inclusive.

Exceptions

RangeError

Thrown if thebyteOffset is set such that it would read beyond the end of the view.

Examples

Using getInt16()

const { buffer } = new Uint8Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);const dataview = new DataView(buffer);console.log(dataview.getInt16(1)); // 258
