I’m trying to understand how the map() method works in JavaScript when iterating over arrays. How does it transform each element differently compared to other iteration methods?
The map() method in JavaScript creates a new array filled with the results of calling a provided function on every element in the original array. I’ve used map() in various projects to transform data without altering the initial array, which promotes immutability. It differs from simple iteration like for loops primarily because it returns a new array, making it easier to work with and chain functions. Its functional style often leads to cleaner, more reusable code, especially when dealing with transformations and data mapping.
