What's coming to JavaScript

TC39's 108th meeting advanced 9 JavaScript proposals across different stages. Key features reaching stage 4 include explicit resource management with the `using` keyword for automatic cleanup, `Array.fromAsync` for handling async iterables, and `Error.isError` for reliable error detection. Stage 3 introduces immutable ArrayBuffers for safer binary data sharing. Stage 2 proposals include seeded random number generation and `Number.prototype.clamp` for value bounding. Stage 1 features focus on number formatting improvements, standardized value comparisons, and enhanced random utility functions. These additions aim to make JavaScript more powerful, safer, and developer-friendly.
