Node.js - buffer module

// Allocate buffer of size 15 filled with 'b'
const bufferAlloc = Buffer.alloc(15, 'b');

// Create buffer1 with 'hello' and buffer2 with 'world'
const buffer1 = Buffer.from('hello');
const buffer2 = Buffer.from('world');


// Combine buffer1 and buffer2
const bufferArray = [buffer1, buffer2]
const bufferConcat = Buffer.concat(bufferArray);

// Translate buffer to string
const bufferString = bufferConcat.toString();


console.log(bufferAlloc);  // will print 62 hexadecimal code for letter 'b'
console.log('Buffer 1:', buffer1, 'Buffer 2:', buffer2)  // each printed represents the hexadecimal of the letters
console.log(bufferConcat);
console.log(bufferString); //then show the words combined in string form
