How does safe-buffer.byteLength work?

The safe-buffer.byteLength function is a utility function that computes the byte length of a given string, buffer, or array. It handles the edge cases where the input is null, undefined, or not a string/buffer/array, returning 0 for those cases. When the input is a string, it returns the number of bytes the string would occupy when encoded using utf8.

const { byteLength } = require("safe-buffer");

const str = "Hello, world!";
const buffer = Buffer.from(str, "utf8");

console.log(byteLength(str)); // output: 13
console.log(byteLength(buffer)); // output: 13

In this example, we require the byteLength property from the safe-buffer module. We then create a string and a buffer with the same value and use the byteLength property to get the byte length of both. The output should be 13 for both the string and the buffer, as they contain the same number of characters.
