Below examples illustrate the use of v8.serialize() method in Node.js.

Example 1: Filename: index.js

// Accessing v8 module
const v8 = require('v8');

// Calling v8.serialize()
console.log(v8.serialize("geeksforgeeks"));

Run index.js file using the following command:

node index.js

Output:

<Buffer ff 0d 22 0d 67 65 65 6b 73 66 6f 72 67 65 65 6b 73>

Example 2: Filename: index.js

// Accessing v8 module
const v8 = require('v8');

// Calling v8.serialize()
serialized_data = v8.serialize("abcdefg");
console.log("\nSerialized data is ");
console.log(serialized_data);

serialized_data = v8.serialize(58375693);
console.log("\nSerialized data is ");
console.log(serialized_data);

serialized_data = v8.serialize(73847.0234);
console.log("\nSerialized data is ");
console.log(serialized_data);

serialized_data = v8.serialize('\n');
console.log("\nSerialized data is ");
console.log(serialized_data);

Run index.js file using the following command:

node index.js

Output:

Serialized data is
<Buffer ff 0d 22 07 61 62 63 64 65 66 67>

Serialized data is
<Buffer ff 0d 49 9a f8 d5 37>

Serialized data is
<Buffer ff 0d 4e ac ad d8 5f 70 07 f2 40>

Serialized data is
<Buffer ff 0d 22 01 0a>
