Using async/await modernizes asynchronous control flow and simplifies error handling across web apps and Node.js services. This pattern replaces nested callbacks with linear code, making your logic easier to read and maintain.

Using destructuring, spread, and rest operators is the best way to handle immutable data updates in modern JavaScript. These ES6+ features allow you to concisely copy and extract object or array properties without mutating the original data.

You need iterators and generators in a web app or Node.js codebase when building scalable, lazy, and modular data flows. They allow you to process large datasets incrementally without loading everything into memory at once.

Functional programming improves testability and composition in ES6+ JavaScript modules. By applying pure functions and modular patterns, developers can isolate logic, reduce side effects, and build highly predictable codebases.

You can use modern ES6+ patterns for performance tuning in existing libraries. Refactoring legacy code with advanced features like modules and enhanced object literals optimizes execution and modernizes the codebase for better efficiency.
