Using native functions such as map, filter, and reduce provides a more readable, concise, and maintainable solution. They leverage the principles of functional programming, enhancing code clarity and reducing the risk of errors. This approach also benefits from optimizations within the JavaScript engine, potentially leading to better performance.

Mastering JavaScript functions like map, filter, and reduce is crucial for anyone pursuing a career in programming, as they allow for powerful and flexible data manipulation, which is essential for building modern applications.

The filter function is ideal for situations where you want to exclude certain elements or focus only on elements that meet particular conditions.

The map function is particularly useful in scenarios where you want to perform operations like scaling numerical values, formatting strings, or extracting specific properties from objects within an array.

The reduce function is suitable for operations that combine array elements into a summary result, such as calculating sums, products, or more complex accumulations like building a frequency map.
