Arrays are fundamental data structures in JavaScript, allowing developers to store and manipulate collections of data efficiently. Understanding how to work with arrays is crucial for any JavaScript developer, and mastering array methods can greatly enhance your coding skills.

In this article, we will explore some essential array methods in JavaScript that will help you manipulate arrays effectively.

Introduction

JavaScript provides a rich set of built-in methods for working with arrays. These methods allow you to perform common operations such as adding or removing elements, iterating over arrays, filtering elements based on certain criteria, and transforming arrays in various ways. By mastering these array methods, you can write cleaner, more concise code and improve the efficiency of your programs.

1. forEach()

The forEach() method executes a provided function once for each array element.

const numbers = [1, 2, 3, 4, 5];

numbers.forEach((number) => {
  console.log(number);
});
