In JavaScript, choosing between forEach, map, and traditional for loops ultimately depends on the context and desired outcome. The forEach method is perfect for executing a function on each array element without needing a returned value, making it easy to read for simpler operations. The map method is ideal for transforming data and returning a new array, clearly indicating the intent of array manipulation. In contrast, traditional for loops offer maximum flexibility, allowing complex control over iterations, making them suitable for scenarios requiring more than just simple operations.
When optimizing for readability, both forEach and map have their advantages; forEach is simpler for performing operations, while map clearly indicates array transformations.
The for loop provides the most control and can handle complex logic within the loop, making it a versatile choice in many scenarios.
