For Each Loop

A for each loop is a programming control flow statement that iterates over elements in a collection, such as an array, list, or set, without requiring explicit indexing. It simplifies code by automatically handling the iteration process, making it more readable and less error-prone compared to traditional for loops. This construct is widely supported in many programming languages, often with specific syntax like 'for...in' or 'for...of'.

Also known as: for...in loop, for...of loop, enhanced for loop, foreach, iterative loop
🧊Why learn For Each Loop?

Developers should use for each loops when they need to process every element in a collection sequentially, such as when performing operations on items in a list or filtering data. It is particularly useful in scenarios where index-based access is unnecessary, reducing boilerplate code and minimizing off-by-one errors. For example, in data processing tasks or when working with iterable objects in languages like Python, JavaScript, or Java.
