How do different programming languages handle array iteration?

How do different programming languages handle array iteration?

Different programming languages have various methods for iterating over arrays. For example, in JavaScript, you can use the forEach method, while in Python, you can use a simple for loop.

Can you give me examples of array iteration in Java and C++?

Sure! In Java, you can use an enhanced for loop like this: for (int num : array) { System.out.println(num); }. In C++, you can use a range-based for loop: for (auto num : array) { std::cout << num; }.

What about functional programming languages?

In functional programming languages like Haskell, you can use the map function to apply a function to each element in an array. For example: map (+1) [1,2,3] would return [2,3,4].

Are there any performance differences in these methods?

Yes, performance can vary based on the method used and the language's implementation. Generally, traditional loops are faster than higher-order functions like map due to less overhead.
