**`Zlib`** is a built-in module in Node.js that provides compression or decompression properties on texts and buffers in a program.

We use the **`zlib.createDeflateRaw()` module** to create a new #key# DeflateRaw: a module in the Zlib that we use to compress chunk of data. #key# object. The `createDeflateRaw()`  module was added in version v0.5.8 of Node.js.

## Syntax
```nodeJS
zlib.createDeflateRaw( options )
```
The function accepts only a single parameter that specifies the different options of a `Zlib` object. It returns the created `DeflateRaw` object. 

## Use
We can implement the `createDeflateRaw()` module in the program using the following syntax:

``` node.js
const obj_defraw = zlib.createDeflateRaw(); 
```
We have to create a new object for this function to use in the future.

## Code

To better understand how to implement a `createDeflateRaw()` method, let's observe the following example code.

const zlib = require('zlib');

var obj1;
var def_raw1 = zlib.createDeflateRaw(obj1).toString('utf8');

var obj2;
var def_raw2 = zlib.createDeflateRaw(obj2);

console.log(def_raw1);

console.log("\n", def_raw2);


## Explanation

The above illustration demonstrates two objects that hold no data: `obj1` and `obj2`.

Objects `def_raw1` and `def_raw2` use these objects to create new objects for `DeflateRaw`. We have passed these objects as parameters into the `createDeflateRaw()` method. 

The output for `def_raw1` displays the object and its type class in `utf8` format, whereas `def_raw2` returns the JSON type for `obj2`. All properties of the new object created using `def_raw2` are listed in the console log.
