The new "using" keyword a.k.a ECMAScript Explicit Resource Management in JavaScript transforms how you handle resource cleanup, and may eliminate your need for try-finally blocks forever. This Node.js 24 feature automatically manages resource disposal at the end of scope, similar to patterns in Python, Java, and C#. Learn how this elegant solution works with file handling, database connections, and test environment setup. While JavaScript continues to evolve with new features like composites, pipe operators, and structs, this practical addition offers a cleaner approach to resource management that can significantly improve your code.
