To refactor legacy JavaScript to ES6+, replace traditional functions with arrow functions, use destructuring and spread/rest operators, and adopt template literals. This process yields cleaner, more maintainable, and efficient code by leveraging modern JavaScript features.

The best way to handle asynchronous data fetching in modern JavaScript is using Promises and async/await. These features allow you to write asynchronous operations sequentially without deep nesting, resulting in clean and readable code that efficiently handles data retrieval.

Build data transformation pipelines using functional programming by chaining array methods like map, filter, and reduce. Combining these higher-order functions through functional composition allows you to process data immutably, creating robust and maintainable transformation flows.

Benefits of using arrow functions and destructuring in ES6 include shorter syntax and lexical scoping of the `this` keyword. Destructuring allows concise extraction of object properties and array elements, significantly reducing boilerplate code and improving overall readability.

Yes, you can use modern JavaScript array methods like map, filter, and reduce instead of traditional loops. These higher-order functions enforce immutability and enable functional composition, which produces robust data transformation pipelines with fewer side effects.
