On the flip side, opt for the forEach method when your focus is on performing an action on each element of the array without the need to create a new array. This method is ideal for scenarios where you’re modifying properties, logging data, or making changes directly within the array. Keep in mind that the forEach method doesn’t return anything, so it’s about making changes in place.

Optimizing Code and Performance

Streamlining with Map

One key advantage of the map method is its ability to streamline your code and reduce redundancy. Instead of manually creating a new array and populating it with transformed data, the map method handles this process elegantly. This not only enhances code readability but also reduces the chance of errors when dealing with complex data transformations.
