What is values() in Node.js Buffer Module?

The `values` function in Node.js Buffer Module

The **`values`** function is a member function of `Buffer` class in the Node.js Buffer Module. The `values` function is called on an instance of `Buffer` and returns an `Iterator` for the bytes in the instance. The syntax of the `values` function is as follows: ```js buf.values() ```

Parameters

`values` takes no parameters.

Return value

- Returns an `Iterator` for values of `buf`.

Description

The `values` function creates and returns an `Iterator` for the values of the buffer `buf`.

Example usage of the `values` function

The following code snippet provides an example of how to use the `values` function:
const b = Buffer.from('ABCXYZ');
for (const v of b.values()) {
  console.log(v);
}

In the above example, b is a Buffer instance of length 6 that contains utf-8 encoded bytes for the string ABCXYZ. The b.values() function returns an Iterator, which is stored in v. In every iteration of the for loop, the value of v is printed, which is basically an integer value for a byte of buffer b.

Note: In a for...of construct, b.values() is unnecessary as b itself would also return a value Iterator in this case.
