JavaScript arrays are powerful data structures that allow developers to store multiple values in a single variable. But when we pair them with objects, their utility in real-world applications—such as managing user data, processing orders, or handling any collection of entities—becomes even more significant. In this blog post, we’ll dive deep into some of the most useful array methods, showcasing them through practical examples that use arrays of objects. This approach will help you see the real-world applicability of these methods in web development and beyond.
Adding and Removing Elements
Push & Pop: Managing the End of an Array
Push adds one or more elements to the end of an array and returns the new length of the array. Pop, on the other hand, removes the last element from an array and returns that element.
let users = [{ name: "Alice" }, { name: "Bob" }];
users.push({ name: "Charlie" });
// [{ name: "Alice" }, { name: "Bob" }, { name: "Charlie" }]
users.pop();
// [{ name: "Alice" }, { name: "Bob" }]
