Buffer Module in Node.js provides access to Buffer objects that represent fixed-length sequences of bytes. readUInt16BE()
is a method defined in the Buffer Class that reads a 16-bit, big-endian unsigned integer from the Buffer object starting from the specified offset. The prototype of readUInt16BE()
is as follows:
buf.readUInt32BE([offset])
offset
: Number of bytes to skip before reading. offset
must be an integer and lie in the range . The default value is .
16-bit, big-endian unsigned integer from buf
starting from the specified offset.
NOTE: Buffer Class is accessible within the global scope. Therefore, you do not need to use the
require('buffer').Buffer
method to import the Buffer Module.
const buf = Buffer.from([1, 62, -83]);console.log(buf.readUInt16BE(1));
In the first line, we create the buffer object buf
using Buffer.from()
. Then, we display the 16-bit, big-endian unsigned integer from buf
after skipping 1 byte by passing offset
1 to the buf.readUInt16BE()
method.
