Buffer

What is Buffer? you can read my repository here.

1. Create Buffer from String

   const buf = Buffer.from("hello world", "utf8");
   console.log(buf); //<Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>

2. Check Buffer Object

   console.log(typeof buf); //object
   console.log(buf instanceof Buffer); // true

3. Convert Buffer to Base64 String

   console.log(buf.toString("base64")); //aGVsbG8gd29ybGQ=

4. Convert Buffer to Hex

   console.log(buf.toString("hex")); //68656c6c6f20776f726c64

5. Convert Buffer to ASCII

   console.log(Buffer.from("SGVsbG8gV29ybGQ=", "base64").toString("ascii")); //Hello World
