How do different programming languages handle iteration?

How do different programming languages handle iteration?

Different programming languages have various constructs for iteration, such as loops and iterators. For example, Python uses 'for' and 'while' loops, while Java has 'for', 'while', and enhanced 'for' loops.

Can you give examples of iteration in Python and Java?

Sure! In Python, you can use a 'for' loop like this: for i in range(5): print(i). In Java, you might write: for(int i = 0; i < 5; i++) { System.out.println(i); }.

What about functional programming languages?

Functional programming languages like Haskell use recursion and higher-order functions for iteration. For instance, you can use the 'map' function to apply a function to each element in a list.

Are there performance differences in iteration methods?

Yes, performance can vary based on the language and the specific iteration method used. For example, using built-in functions in Python can be faster than manual loops due to optimizations.
