• crypto.randomBytes is part of Node.js, so it requires no external dependencies. This makes it ideal for Node.js environments where minimal dependencies are desired.
• ethers.randomBytes requires the installation of the ethers.js library, which is primarily designed for blockchain-related projects. This is useful if you're already working with Ethereum, but it adds an external dependency to the project.

• crypto.randomBytes:
• Takes a single argument specifying the number of bytes.
• Always requires a size input; no default value is provided.
• ethers.randomBytes:
• Optionally takes the number of bytes to generate.
