Node.js - v21.3.0

Notable Changes

New --disable-warning flag

This version adds a new --disable-warning option that allows users to disable specific warnings either by code
(i.e. DEP0025) or type (i.e. DeprecationWarning, ExperimentalWarning).

This option works alongside existing --warnings and --no-warnings.

For example, the following script will not emit DEP0025 require('node:sys') when executed with
node --disable-warning=DEP0025:

import sys from 'node:sys';

Fast fs.writeFileSync with UTF-8 Strings

Enhanced writeFileSync functionality by implementing a highly efficient fast path primarily in C++ for UTF8-encoded string data.
Additionally, optimized the appendFileSync method by leveraging the improved writeFileSync functionality.
For simplicity and performance considerations, the current implementation supports only string data,
as benchmark results raise concerns about the efficacy of using Buffer for this purpose.
Future optimizations and expansions may be explored, but for now, the focus is on maximizing efficiency for string data operations.
