Parameters: This method accepts single parameter as mentioned above and described below:

• length: It is a required parameter, refers to the length of the buffer to be read from deserializer's internal buffer.

Return Value: This method reads raw buffer data from deserializer's internal buffer and returns it as buffered data.

Below examples illustrate the use of v8.Deserializer.readRawBytes() method in Node.js:

Example 1: Filename: index.js Run index.js file using the following command:

node index.js

Output:

<Buffer ff 0d 49 ae 5a>
<Buffer ff 0d 49 ae 5a>

Example 2: Filename: index.js Run index.js file using the following command:

node index.js

Output:

<Buffer ff 0d 49 84 d0 03 ff 0d 22 0d 67 65 65 6b 73 
66 6f 72 67 65 65 6b 73 ff 0d 49 84 d0 03>
<Buffer ff 0d 49 84 d0 03>
<Buffer ff 0d 22 0d 67 65 65 6b 73 66 6f 72 67 65 65 6b 73>
<Buffer ff 0d 49 84 d0 03>
