HOW

Buffer.from creates Buffer from string with default utf8 encoding
Buffer.from creates Buffer from string with hex and base64 encodings
Buffer.from creates Buffer from byte array
Buffer.from creates Buffer copy from existing Buffer
Buffer.from creates Buffer from ArrayBuffer with byteOffset and length
Buffer.alloc creates zero-filled buffer of specified size
Buffer.alloc creates filled buffer with custom fill value
Buffer.allocUnsafe creates uninitialized buffer of specified size
Buffer.isBuffer returns true for Buffer instances and false for non-buffers
Buffer.isEncoding returns true for valid encodings and false for invalid encodings
Buffer.concat joins multiple Buffer instances into a single Buffer
Buffer.byteLength returns byte length of strings across different encodings
Buffer.compare orders buffers lexicographically
Buffer instance supports write, toString, toJSON, slice, and binary read/write methods
Buffer.from throws TypeError when value is a number
Buffer.from throws TypeError when encoding is unknown
Buffer.alloc throws RangeError when size is negative
Buffer.alloc throws TypeError when size is not a number
Buffer.concat throws TypeError when list is not an Array
