How does lodash.isBuffer work?

lodash.isBuffer is a method in the Lodash library that checks if a value is a buffer object. When you call lodash.isBuffer(value), the function returns true if value is a buffer object and false otherwise. A buffer object is an object that represents a fixed-size chunk of memory, typically used for working with binary data. The function checks whether value has a .buffer property and whether the typeof that property is 'object'. If both of these conditions are true, the function returns true. In essence, lodash.isBuffer provides a way to test whether a given value is a buffer object, allowing you to perform checks on binary data in JavaScript.

const _ = require("lodash");

const buffer = Buffer.from("hello world");
const isBuffer = _.isBuffer(buffer);

console.log(`Is buffer: ${isBuffer}`);

In this example, we first import the lodash library. We then create a Buffer object using Buffer.from('hello world'). We then call _.isBuffer(buffer) to check if buffer is a buffer object. The function returns true, since buffer is indeed a buffer object. Finally, we log the result to the console. Note that in this example, we're using a Buffer object as the argument to _.isBuffer(). You can use other values as well, but they will not be recognized as buffer objects and _.isBuffer() will return false.
