Buffer Allocation
The Buffer.alloc()
and Buffer.allocUnsafe()
methods are used to allocate memory for new buffers. Buffer.alloc()
initializes the buffer with zeros, ensuring that sensitive data is not exposed, while Buffer.allocUnsafe()
allocates uninitialized memory, providing better performance but potentially exposing sensitive data.
// Allocating memory for a buffer
const buffer = Buffer.alloc(10); // Initialize with zeros
// Or
const unsafeBuffer = Buffer.allocUnsafe(10); // Uninitialized memory
What is the purpose of the Buffer class in Node ?
In Node, the Buffer
class plays a crucial role in handling binary data, allowing developers to work with raw binary data directly. The Buffer
class provides a way to create, manipulate, and convert binary data efficiently, making it essential for various tasks such as file I/O, network communication, cryptography, and data manipulation. Let’s explore the key purposes and functionalities of the Buffer
class in Node.
