Hello, Dev community! Today, we’re diving into one of the core concepts in JavaScript: array iteration. Whether you're just starting out or brushing up on your skills, understanding how to effectively iterate over arrays is crucial. Let's get started!

What is Array Iteration?

Array iteration refers to the process of accessing each element of an array, one by one, in a sequential manner. JavaScript provides several built-in methods to achieve this.

1. for Loop. The for loop is one of the most traditional ways to iterate over an array. It provides complete control over the iteration process.

1. for...of Loop The for...of loop is a more modern and concise way to iterate over iterable objects, including arrays.

1. forEach Method The forEach method executes a provided function once for each array element. It's straightforward and keeps your code clean.

1. map Method The map method creates a new array populated with the results of calling a provided function on every element in the calling array.

1. filter Method The filter method creates a new array with all elements that pass the test implemented by the provided function.

1. reduce Method The reduce method executes a reducer function on each element of the array, resulting in a single output value.

those are some of the commonly used methods.
