**Buffer Module** in Node.js provides access to Buffer objects that represent fixed-length sequences of bytes. **`readUInt32BE()`** is a method defined in the Buffer Class that reads a 32-bit, [big-endian](https://www.linuxjournal.com/article/6788) unsigned integer from the Buffer object starting from the specified offset. The prototype of `readUInt32BE()` is as follows:
```JavaScript
buf.readUInt32BE([offset])
```
# Parameters

**`offset`**: Number of bytes to skip before reading. `offset` must be an integer and lie in the range $0<= offset <= buf.length -4$. The default value is $0$.

# Return value
32-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.

# Example






const buf = Buffer.from([1, 62, -83, 4, 25]);

console.log(buf.readUInt32BE(1));

# Explanation
In the first line, we create the buffer object `buf` using `Buffer.from()`. Then, we display the 32-bit, big-endian unsigned integer from `buf` after skipping 1 byte by passing `offset` 1 to the `buf.readUInt32BE()` method.

What is readUInt32BE() in the Node.js Buffer Module?

readUInt32BE() reads 32-bit, big-endian unsigned integers from Node.js Buffer objects starting at the specified offset.
