If you are working with arrays in modern languages like JavaScript or Python, try to favor built-in functional methods over traditional `for` loops for transformation and filtering. Instead of initializing an empty array and mutating it inside a loop, use `.map()` for transformation (e.g., changing data structure) and `.filter()` for selection (e.g., getting only items that meet a condition). This declarative approach makes your code significantly easier to read, less verbose, and much less prone to side effects, adhering to cleaner functional programming standards.
