Decodes a buffer to a string using the given encoding.
Syntax
buf.toString([encoding[, start[, end]]])Parameters
| Name | Type | Required | Description |

encoding | string | No | Target encoding (default `'utf8'`); also `'hex'`, `'base64'`, `'latin1'`. |
start | number | No | Byte offset to start decoding. |
end | number | No | Byte offset to stop decoding. |
Returns
string — The decoded string.
Examples
const buf = Buffer.from([0x68, 0x69]);
console.log(buf.toString('utf8'));
Output
hi
const buf = Buffer.from('secret');
console.log(buf.toString('base64'));
Output

Notes
Decoding a slice that splits a multibyte UTF-8 character produces a
replacement character; for chunked streams use `string_decoder` to
handle boundaries correctly.
